What will you do when this situation happens to you....???.




Twins from Diffrent fathers

The Encyclopedia Britannica notes that twins are defined as, "… two young who are simultaneously born from one mother." There is no mention that such twins must be of the same father. The advent of DNA testing has turned up more and more cases of twins with two different fathers.

Evidence from Researches

The head of the gynecology department at Ankara University, Professor Rusen Aytac comments that heteropaternal superfecundation is not common in humans (2008). In order for this type of multiple pregnancy to occur, a [FONT=inherit!important]womanhttp://www.pregnancy-info.net/twins-with-two-different-fathers.html would have had to release multiple ova in the course of a single cycle and have sexual intercourse with multiple partners within a small time span.

Different Fathers
While heteropaternal superfecundation is quite rare among humans, it happens often in cats and dogs. Stray dogs have been known to whelp litters in which every puppy is from a different father. The uncommonness of this type of pregnancy among humans is due to their monogamous and heterosexual tendencies. However, it is definitely possible for a woman who has sexual relations with more than one man at short intervals during the same period of ovulation to become impregnated by two or more [FONT=inherit!important]menhttp://www.pregnancy-info.net/twins-with-two-different-fathers.html.[/FONT]

The first recorded case of heteropaternal superfecundation was noted by John Archer in 1810. Archer, an American physician, wrote of a white woman who had sex with a white man and a black man within a short time span. The woman gave [FONT=inherit!important]birthhttp://www.pregnancy-info.net/twins-with-two-different-fathers.html to one white twin and one mixed-race twin.[/FONT]

There is a known case in which heteropaternal superfecundation occurred as a result of fertility treatments. A mix-up in the laboratory during an IVF procedure performed in Holland meant that equipment was used twice. This caused another man's sperm to mix in with that of the woman's husband and resulted in the births twins of different fathers.

Twins Have Different Fathers
A Croatian woman who slept with two men at the same time has given birth to twins with two different fathers. The 23-year-old student, who has been named only as M B, gave birth to non-identical twins in Zagreb seven months ago. However, she has revealed that DNA testing has shown the children have different fathers.
She told daily Jutarnji List, "I was shocked at getting pregnant and even more surprised when doctors told me that my two sons had different fathers." Doctors have said twins being born to different fathers is extremely rare.

Twins Have Different Dads
A Chinese man is suing for divorce after discovering that he is the father of only one of his twins. Liu Yuan of Nanjing city says he noticed the difference between the babies the day they were born, reports Longhu Network. "The baby that came out first was much bigger than the second, who was very weak and sickly," he said.
Liu says he started to be suspicious when the smaller baby turned out to have a different blood type, along with the fact that it doesn't look like him. Liu had his own and the two babies' DNA tested - and discovered that he was the biological father of only the bigger twin. "My wife admitted that she'd had sex with her former boyfriend after we got married," he said.
Doctors explain that it's quite rare, but possible, since a man's sperm can survive for 72 hours in a woman's body.

Twins With Two Different Fathers



Black and White Twins

When Kylie Hodgson gave birth to twin daughters by caesarean section, she was just relieved that they had arrived safely. It was only when the midwife handed them over for her to hold that she noticed the difference between them. Remee, who weighed 5lb 15oz, was blonde and fair skinned. Her sister Kian, born a minute later weighing 6lb, was black. "It was a shock when I realised that my twins were two different colours," said Kylie, 19. "But it doesn't matter to us - they are just our two gorgeous little girls."
Twins in Black and Orange and White...

Cubs Jinliang and Yinshuai aren't any ordinary twins. Workers at Tianjin Zoo, China were shocked when the pair were born - because they arrived in completely different colours - yellow and white. Their mother, Meimei, was a mixed-blood tiger - and it seems each of her offspring unusually inherited each of her different colours...
Semi-Identical Twins

Twins normally share either half or all their genes
Doctors have discovered the world's first known case of "semi-identical" twins. The two young children, conceived normally in the US are identical on their mother's side but share only half the genes of their father's side. They are the result of two sperm cells, one X and one Y, fertilising a single egg, which then divided to form two embryos - and each sperm contributed genes to each child. Each stage is unlikely, and scientists believe the twins may be unique (although if both of the sperm had been X or both had been Y, the condition may never have come to anyone's attention
