Can both twins have babies?

The answer is quite simple. “[Two sets of] identical twins will not have identical offspring,” says Professor Rodney Scott, head of medical genetics at the University of Newcastle. The only way we get identical offspring is when a fertilised egg splits into two cells.

Is there a third type of twin?

A Third Type of Twin In fraternal, or dizygotic, twins, two different eggs are fertilized by two different sperm. With semi-identical twins, an egg is fertilized by two sperm, forming a triploid, which then splits in two. The first sesquizygotic twins were identified in 2007.

But there is no concrete scientific evidence that suggests twins skip a generation.

What do you call twins that look different?

fraternal twins. Identical twins, also called monozygotic twins, develop from a single fertilized egg. … But even though these twins have the same DNA, certain environmental factors, like placement in the womb, can affect each baby’s appearance, making them look slightly different from each other.

Who carries the twin gene?

While men can carry the gene and pass it on to their daughters, a family history of twins doesn’t make them any more likely to have twins themselves. 3 But, if a father passes on the “twin gene” to his daughter, then she may have a higher chance than normal of having fraternal twins.
