The shocking part is this: the woman must have intercourse with the different men in a very small time frame. This is the fourth such story I've come across in the last two years. Most recently we learned of a mom in Dallas, TX whose sons have different fathers. Here's a story about those twins.
What are the odds? Scientist say that the odds are a million to one. There are currently about 7 billion people on earth. Which means that there could be 7,000 sets of twins out there who have different fathers. This is possible, but not probable. Statistics remind us to take into account how likely it is that a women is having intercourse with more than one man during the very small window of time that she will get pregnant. Most women probably aren't.
The sudden increase in the number of these cases could mean that scientists are wrong, and the odds are actually much better than a million to one. It could also mean that women are becoming much more promiscuous. No matter what the cause, the moral of the story is clear. If you have twins, or could possibly be the father of twins, the only way to know for sure who the father is of BOTH is to test them both.
An added bonus of having both twins tested? You'll know for sure if they are identical. Doctor's use an inspection of the placenta(s) to determine if twins are identical or not. Quite often during multiple births the placenta(s) are damaged making it difficult to be sure. A DNA test gives 100% certainty.
Here's a set of famous twins: Mary-Kate Olsen and Ashley Olsen
