What combinations would be needed to cause the development of dizygotic twins?
Dizygotic twins, also known as fraternal twins, result from the release and fertilization of two separate eggs by two separate sperm. Therefore, the combination needed is for a woman to release two eggs during ovulation and for both eggs to be fertilized by different sperm, leading to the development of dizygotic twins.
What side of the family does twins come from?
There really isn't a 'gene' for twins. However, fraternal twins are the result of a woman releasing two eggs at a time. This trait can run in the womens side of the family so there is more chance her daughters will release 2 eggs at a time. To date there is no indication that identical twins have any genetic markers. All women have a chance of having their eggs split and having identical twins.
Do most pregnancies start out as twins?
No, most pregnancies do not start out as twins. When the ovaries release two eggs and both are fertilized then will twins be born (fraternal/nonidentical twins). Or a fertilized egg may divide before implantation resulting in identical twins.

Can a girl release two eggs and miss her next period?
Sure, if she get pregnant.
Can you have twins if your husbands grandmother was a twin?
Identical twins are 100% random, and fraternal twins (two eggs, two sperm) only have to do with the mom's genetics (the one who drops both eggs). The father really has nothing to do with making twins.
Which type of twins develop from two fertilized eggs?
Twins from different eggs are fraternal twins. They are siblings with the same birthdate. They are twins, but not identical, and can even be girl and boy. It is the same process taking place as a single child that a woman becomes pregnant with, but the process happens with two children at the same time. The woman releases two eggs that month instead of one, and they both are fertilized. That is how this type of twin is produced.
How many eggs and how many sperm are there in fraternal twins?
11 sperms and 21 eggs
