If a woman sleeps with different men in a short period of time, it can happen that each egg is fertilised by different semen.

American Mia Washington admitted she had an affair at the time when she became pregnant, so what happened to her is something that is very unusual indeed. Two of her eggs were fertilised with two different sperm, making her the mother of twins with two different fathers, telegraph.co.uk reported.

Her partner James Harrison had a DNA analysis done when he noticed that the twins Justin and Jordan were very physically different.

Of all the people in the world, it happened to me, the shocked Mia said when she read what the chances of twins not having the same father are – 99.999 percent.
Staff at the laboratory that did the DNA analysis said they never encountered such a case before and they believe they never will again. One doctor said that there is only a handful of cases like this one in the world and that it will probably be the only such case in Dallas.

Mia’s fiancé James will stay with Mia and has forgiven her for being unfaithful. He has promised to take care of the twins as if they were both his.

They will explain to the twins what happened when they are old enough to understand, presumably none of them uses Google.
