Dada kama mmeo ametumia kigezo hicho itakuwa amekosea sana, ama may be hujamuelewa vyema maelezo yake. Mtoto siku zote anachukua genes toka kwa pande zote mbili za wazazi. Huyo wa kwanza itakuwa amematch na wazazi wote wawili ndio maana hana shaka.

Ila kwa kesi yako, hata kama mtoto angezaliwa na group AB ama O, sidhani kama ingekuwa ni sahihi, na angekuwa pia na wasiwasi ingawaje ndio group zenu wazazi.

Wewe hapo fuata ushauri wa watu8, na ikithibitika hivyo, may be wewe na familia yako mnaweza kuwa case study/reference kwa vizazi vijavyo.

ntaufuata huo ushauri mkuu asenten wote
 
Mkuu bantulile, unaweza ukawa na point lakini ukawa umeipoteza kwenye maelezo meeeengi ambayo hayana maana kwa kesi iliyopo hapa! Hapo kwenye red sikuelewi kabisa mkuu unachotaka kuniambia kwani nilichosema kwa mujibu wa taarifa aliyotupa mtoa mada, data zinatufanya tujue ni kwamba watoto watakaowazaa ni group A (AO) ama B (BO), na si vinginevyo, hii ni kutoka kwenye elimu ya blood group.
Blood group ni initial stage ya kujua hawa ni watoto wako endapo alleles zenu wazazi mkizicross F1 generation zitacontain product za alleles zenu kitu ambacho hakipo kwa kutumia data za huyu dada. Hata hivyo hii isiwe final decision ya kuwa watoto ni wako hata kama watoto wenu damu zao zinacontain alleles zenu kwani mwanamke anaweza akachepuka na kupata ujauzito kutoka kwa mwanaume mwenye blood group kama yako! Hapo ndipo inapokuja issue ya kufanya DNA analysis ili kujiridhisha kwamba hawa watoto kweli ni wako?! Vinginevyo iwe kweli alivyosema kaka watu8 kwamba huyu dada, mumewe pamoja na mtoto mmoja wapo ama wote walipewa majibu ya uongo au specimen zao huko laboratory zilichanganywa na za wengine hiyo wakapewa majibu yasiyo yasiyotokana na specimen zao!
Kwa taarifa yako wewe mwenyewe kati ya watoto wako angekuwepo wa group A ama AB ungekuja hapa kutulilia tukueleze kama hao watoto ni wako! Na kweli kama una wa group A na AB basi hao hawatakuwa watoto wako! na kwa kumalizia tu hata hao watoto unaweza ukakuta si wako kwani mkeo akichepuka na jamaa lenye group kama lako we utabaki unalipa school fees tu! Kwa hiyo hata kesi yako si valid hapa, DNA analysis has the final answer! OTHERWISE UKUBALI KUCHAPIWA NI SIRI YA NDANI! Pia uwe unatoa hoja kwa maelezo yako siyo kukopi page zima kutoka kwenye internet then unaibuka kwa tambo na kuponda wachangiaji!!!

Kama huna taaluma ya jambo husika bora usichangie Little knowledge is more dangerous than no knwledge at all. Blood group haihusiki kabisa katika kuthibitisha mtoto ni wa nani. Kinachothibitisha nasaba ni DNA. Mtoto anaweza kuchukua Bood group ya yeyote kutoka upande mmojawapo aidha kwa shangazi, mjomba babu bibi nk. Mimi ni B[SUP]+ [/SUP]mke wangu ni B[SUP]+ [/SUP]nina watoto wenye O[SUP]+ [/SUP]O- B. Watu wenye O[SUP]- [/SUP]Duniani ni wachache mno soma hapa O-Negative Blood Group
O-negative blood group is relatively rare compared to other blood groups. A person with O-negative blood group is a universal donor as O-negative blood can be transfused to any blood group. O-negative blood group has also been associated with certain personality traits.
Blood group is determined by the presence of antigen(s) on the membrane of red blood cells. The "antigens" are special molecules that can elicit an immune response. Human body recognizes its own antigens and the immune system normally will not attack own antigens (and thus the cells bearing these antigens). However, any foreign antigen will not be recognized as native and an immune response will be generated to eliminate the foreign antigens. One of the components of this attack is antibodies (special class of molecules that bind to antigens and helps immune system eliminate foreign antigens and the cells bearing them).
ABO and Rh Blood Group System
ABO blood group and Rh blood group is determined by the presence of three antigens ("A" and "B" for ABO system, "Rh" for Rh system). These two are the most important blood grouping systems and are based on the three most important antigens, i.e. A, B and Rh. It is important to note that the two are two different blood group systems that are quoted in combination. ABO blood group system is determined by the presence of A and B antigen. Rh antigen determines the Rh blood group system category. There are numerous other less important antigens and therefore numerous other blood grouping systems.
A person with "A" blood group will have "A" antigen on the red blood cells and anti-B antibody in the plasma. Similarly, a person with "B" blood group will have "B" antigen on the red blood cells and anti-A antibody in the plasma. A person with "AB" blood group will have both "A" and "B" antigens on the red blood cells and none of the above mentioned antibodies in the plasma(neither anti-A nor anti-B antibody). Blood group "O" means absence of both "A" and "B" antigens and both anti-A and anti-B antibody in the plasma.
The positive or negative in the blood group refers to the Rh antigen. A "positive" blood group means that the person has Rh antigen on the red blood cells whereas a "negative" blood group means that the Rh antigen is absent on the red blood cells. Unlike ABO system, an Rh -ve person will not have anti-Rh antibody in the blood unless he/she has been previously exposed to Rh +ve blood. Soon after birth, newborns develop anti-A and/or anti-B antibodies but not the anti-Rh antibody.
Blood Group​
Antigen (A,B)​
Rh Antigen​
Antibodies​
A+ A Present Anti-B
B+ B Present Anti-A
AB+ A, B Present None
A- A Absent Anti-B
B- B Absent Anti-A
AB- A, B Absent None
O+ None Present Anti-A, Anti-B
O- None Absent Anti-A, Anti-B
Note: Anti-Rh is not usually present in an Rh negative person. It only develops after an exposure to Rh positive blood in a person with Rh negative blood group.
Importance of Blood Group Matching
Blood group matching is important so that the transfused blood is not attacked by the immune system of the recipient. The body will attack any foreign antigen. For e.g., A person with blood group B will be having B antigen on the red blood cells and therefore "A" antigen will be foreign. If any blood type with A antigen (A or AB blood group) is transfused, the immune system will attack such cells and this will result in the breakdown of the newly transfused red blood cells.
A person with AB+ blood group will have all 3 antigens (A, B, and Rh) on his/her red blood cells. Therefore, he can be transfused with any blood group (referred to a "universal recipient"). A person with O-negative blood group will have none of the three antigens, and therefore can only receive O-negative blood group (any other blood group will result in immune attack on the "foreign" antigen). However, this person can donate blood to any blood group person as none of the three antigens is present on the red blood cells.
O-negative Blood Group
As already mentioned, the O-negative blood group means absence of all of the three major antigens ("A", "B" and "Rh") on the red blood cells. It is important to note that there is no "O" antigen on the blood cells. The absence of antigens A and B is referred to as O blood group.
O-negative blood group is relatively rare and its prevalence varies among different races. Around 7-8% of the Caucasian population will have O-negative blood group. However, only 1% of the Asian population will have O-negative blood group. Overall, around 5% of the world's population will have O-negative blood group.
O-negative Blood Group and Pregnancy
A woman with O-negative blood group may have Rh incompatibility issues if she is pregnant with an Rh positive fetus. Complications are likely to occur in second pregnancy with an Rh positive fetus if adequate preventive measures are not taken.
However, adequate prophylactic treatment is available and it almost always prevents the complications if taken at proper schedule. The treatment involves injecting the mother with antibodies against the Rh antigen (RhoGHAM) during pregnancy and at the time of delivery of baby.
O-negative Blood Group and Blood Donation
O-negative blood group is the "universal donor" blood group. This means that a person with any blood group can receive O-negative blood. This is very important in emergency situations when a person requires immediate blood transfusion and there is no time to test his/her blood group. Such person can be transfused an O-negative blood.
People with O-negative blood group can only receive O-negative blood. Therefore, occasionally it might be difficult to find O-negative blood for transfusing an O-negative person.
O-negative Blood Group and Personality Traits
It is believed in Japanese culture that a person's blood group determines his/her personality traits. O-negative persons are believed to be more self confident, loyal, competent and passionate. They are believed to have leadership qualities and are considered innovators and trend setters. However, there is little scientific evidence in favor of this believed association and so far blood group has not been found to affect a person's personality.

Mkuu kama matokeo ya hospitali yakithibitika kwa DNA kuwa mtoto ni wa baba huyo na mama huyo na blood groups ziwe kama hivyo alivyodai huyo mama hii case itakuwaje ? Ishawahi pata tokea kesi kama hii popote pale duniani.?

Mkuu ngoja kuna case study moja ya "Blood Mutation" nafuatilia bila shaka nitakuja na jibu...
 
Huyo baba asikatae majukumu yake bana! Mm binafsi nina O+ mama yangu ana O+ baba ana AB mbona ckupata hiyo A or B? Na kwetu wote tumefanana na babayetu group zetu O kasoro mmoja kapata AB tuko 7. Mtasema hapo mamauangu aliibia njee??
Huyo baba ajiulize wazazi wake walikuwa na group gani za damu asimsumbue mkewe
 
Mhh, hakyanani.............! mkuu watu8, hebu wahi huku ukiipata hiyo ' blood mutation' knowledge make tunazidi kupata za uso huku!!

Mkuu xyz123 kuna case study moja imeshawahi kufanyika ambapo Mzazi mmoja mwenye kundi AB na mwingine mwenye kundi O wanaweza kupata mtoto mwenye kundi O.

Hili jambo sio common na ndio maana linahusishwa na 'blood mutation', na case study ya namna hii imeshawahi fanyika nchi za mashariki ya mbali i.e Korea na Japan.

Hili kundi la damu spesho hutambulika kama cis-AB, ambapo isivyo kawaida huambatana na alleles A, B au O. Yaani mtu wa namna hii anakuwa na AB/A, AB/B au AB/O.

Sasa mtu wa namna hiyo ukimcross na mtu mwingine mwenye kundi OO, AO au BO kuna wa kupata mtoto mwenye kundi O, A, B, AB au cis-AB.

Si ajabu na sisi Tanzania kukawa na watu wenye aina hii ya mutation na pengine habari hii inaweza mpatia ahueni kidogo bi mkubwa huyu kabla hajafanya vipimo zaidi.

NB:
Inaaminika kwa kila Wakorea 100,000 basi watatu wana aina hii ya kundi la damu, wakati kwa kila Wajapan 100,000 basi mmoja pekee ana aina hii ya damu.

Soma hapa link ya kwanza uone namna inavyoelezewa kikemikali, na link ya pili na tatu kwa maelezo zaidi.

1. Genetic mechanism of Cis-AB inheritance. II. Cases associated with structural mutation of blood group glycosyltransferase.

2. Understanding Genetics

Duh..huyo Mama yako nuksi kweli,yaani amembambikiza Mzee wa watu watoto wote 6 kati ya 7?noumer kweli.

Huko kufanana itakuwa ni kwa imagination zenu tu,maana ata mke na mme wakikaa pamoja na kuwa beneti sana baada ya muda utaona kama wanafanana.Ebu check Blood calculator hiyo kwa hisani ya Watu8,Blood Type Child Parental Calculator -- EndMemo, Huyo sio Baba yenu.Mwambieni Mama yenu awaambieni Baba yenu wa ukweli kabla hajafa.
 
Acha ushamba wewe mwanamke mpeleke mtoto kwa baba yake usimbambikizie mtu litoto bwana
 
Mkuu watu8 nimeipitia hiyo makala, na ninaona ndio case inayoingia kwa hawa wakina dada. Vipi CIS AO, BO, na OO zinaexist.? Ama ni kwa AB pekee.?

Nadhani dada hapa amepata ahueni.

Naomba niende kwenye mada moja kwa moja. mimi ni mwanamke nimeolewa miaka mitano iliyopita na tuna mtoto mmoja na huyu mume wangu tatizo hasa lakuomba ushauri kwenu ni mume haamini kama huyu mtoto ni wake because tulipima blood group na mtoto ana group o positive, ambapo mimi na mwanangu tupo group moja yaan hiyo o. na babake ana group AB .

Sasa babaake anasema mtoto si wake haiwezekani mtoto awe group 0 nawakati yeye ni group AB nakosa amani mwenzenu naomba ushauri wenu.ni kweli lazima mtoto afuate group blood kwa baba?

kwanza inavyoonekana wewe mwenyewe hauna uhakika kama mtoto ni wa huyo mume wako ndio maana umeuliza hapa,... kama ungekuwa na uhakika usingeuliza,..
pili maswali kama haya huwa yanaulizwa na wanaume mara nyingi kwa sababu kubwa ni kuwa siri ya mtoto aijuaye ni mama so siku zote wanaume tunalea tu mtoto.,..
tatu kama unakumbuka kama kuna mtu zaidi ya mumeo ulisex nae mtafute maana possibility ya huyo mtoto kuwa wa nje ni kubwa otherwise kama umekosea vipimo vya damu
nne ni impossible narudia tena haiwezekana kwa mtoto kuwa na group o na mzazi mmoja kuwa na AB na mwingine o,..
hitimisho kwa hivyo vipimo ulivyoleta huyo mtoto sio wa mumeo tafuta baba yake mwingine au karudie kupima halafu rudi hapa tena
