Will I have twins if my dad is fraternal twin?

A dad who's one of a twin may inherit the gene, but it won't increase his chances of having twins too, because the gene only affects ovulation. The same dad may pass on the gene to his daughter, who then goes on to get pregnant with twins, making it look like twins have skipped a generation .

Are twins hereditary through the father?

However, few genes appear to be definitively linked to hyperovulation, so it could just be that genetics in general on the mother's side contribute to the probability of having fraternal twins. Heredity on the father's side, on the other hand, does not increase a couple's odds of having twins.

How are twins passed down?

When both eggs are fertilized, the resulting siblings are fraternal twins. Because this gene can be passed on, the tendency to have fraternal twins can in fact run in families. Identical twins, on the other hand, result from one fertilized egg randomly splitting in two, creating two siblings with identical DNA.

What gender is most common in identical twins?

Identical twins are almost always the same sex, although there are some rare exceptions to this rule. Because identical twins occur when a single fertilized egg splits and forms two embryos, each embryo has the same chromosomes (usually, XX for girls or XY for boys).

Can a father pass a twin gene to daughter?

What is this? It is possible for the father to have the twin gene in him which is made possible by his own mother who is a carrier. This can then be passed on to his children. If, for example, his daughter inherits the twin gene, then it is more than possible that he would have fraternal twins as grandchildren.
