Twins were born is it because of Mother's family or father's family?

Answer 1

In order for franternal twins to be born the mother HAS TO release two eggs in the month that she becomes pregnant. If she doesn't release two eggs, then fraternal twins cannot be produced. Men release millions of sperm with each ejaculation and "only the strong survive." Studies show that there is a genetic basis for fraternal twinning. However, it is only the female partner that has any influence on the chances of having fraternal twins as the male cannot make her release more than one ovum.

With that being said, Identical twins are the result of one egg and one sperm splitting. The likelihood of a single fertilization resulting in identical twins appears to be a random event, not a hereditary trait, and is uniformly distributed in all populations around the world. (source http://en.wikipedia.org/wiki/Twins) My sister has two sets of twins. (ALL boys) When doing the genealogy, we found that twins have run on both sides of our families. My brother in law had a grandfather that was a twin and my sister and I have a great grandfather that was a twin.

So with the fraternal twins being separate eggs and sperm, I would have to say that the instance of twins has to be more from the mothers family. Here is another article to back it up.

Answer 2

I am a new mother of a set of fraternal girl twins. (For those who don't know much about twins that means that they do not look alike). I was told by my doctor and every one else that I asked that fraternal twins come from mommy. The mother has produced two eggs. That trait is typically inherited. Identical could be either the guys family or the female. It is one egg that just happened to split in two. Anyone heard different?

Answer 3

as far because of fact the kin trait is going, twins stick to the mummy's line. it frequently skips a era, besides the undeniable fact that woman faternal twins are extra probable to have twins than an same twin. That being stated, the extra pregnancies a female has had and the older she is, she is extra probable to have twins. The above answer is right - same twins are from one egg that splits, on an analogous time as faternal twins are the effect of the girl liberating 2 eggs.

Answer 4

Comes from the Mothers Side

Answer 5

Since twins come from release of 2 eggs, or splitting of one egg into 2, I would definately say it is due to the Mother's genetic predisposition. the father's sperm never comes into play in either scenario.

Answer 6

Depends which side has history of twins running in the family.

Answer 7

the woman choses how many and the man choses the sex

Answer 8

or fertility drugs.....
