Here’s How A Set Of Twins Can Have Two Completely Different Fathers.

If you've seen "Maury", then you know that when it comes to paternity tests, you usually get a straightforward answer. You either are, or you aren't the father. But it's not always so clear cut when it comes to genetics and timing. As rare as it may seem to grasp our heads around the idea, some twins can actually have two different fathers. And you thought suing for child support was complicated with just one dad. Try convincing two separate men that they're the father of your twins. Now that's a little too mind boggling for color TV, but science has definitely backed up this odd occurrence.

Now we all know that only one sperm among million gets to fertilize a single egg cell, which eventually grows into a baby 9 months later.

But there's a condition known as superfecundation, where a woman has sex with two different men while coincidentally, releasing two different egg cells at the same time. What happens next is that the introduction of two separate sets of genes fertilizes the eggs.

Father A will impregnate one egg cell and father B will impregnate the second egg cell.

So in the end, what the twins end up sharing are the genes from their mother, but two totally different genes from their father's side. These sets of twins are known as fraternal, and while it happens between couples with just one father, it's far more complicated when two men are involved in the conception.

Father A will impregnate one egg cell and father B will impregnate the second egg cell.

This particular situation is extremely rare and is often only discovered through a genetic analysis in a lab.

Only then will medical research reveal that a set of twins are in fact bi-paternal, meaning, two men had sex with their mother during the small ovulation window where two eggs were released.

Just ask Charlotte Hilbrandt who slept with her ex-husband Michael and her new boyfriend Tommy within 48 hours.

Given that the twin boys Marcus and Lucas are one of only three known sets of twins in the whole world who are genetic half-brothers, it's safe to say that most people would have had a better chance of winning the lottery than having this happen to them.

In fairness to Charlotte, she had already split up from her hubby on August 2004 when she hooked up with Tommy Kallehauge.

Ironically, neither of the men are upset over the incident and both dads are very much a part of Charlotte's life and the twins they inadvertently conceived together. But the differences are obvious. Marcus is short and stout, red-haired and energetic while Lucas is tall, blonde and is gentler and calmer.
