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.
Why you have twins?
There are two natural ways, one being when u ovulated u had one fertilized egg that split into two, which also would make them identical twins, and two when you ovulated there were two eggs that both got fertilized. Hope this helps. I have identical twins.

How are identical twins genetically from fraternal twins?
Identical twins are genetically the same, because they come from the same fertilized egg/sperm cell zygote, which happens to split into two viable zygotes. Fraternal twins, however, come from two different egg/sperm cell zygotes, that are concurrently fertilized and remain viable.
Do identical twins have to be the same sex?
Yes. Identical twins come from one fertilized egg that has been split in two. Therefore, whatever sex the single egg would've been, the twins will be.
What are the chances of having twins when the father to be is an identical twin and his mother has identical twin brothers?
You have the same chance as the general population. Identical twins are a genetic accident, researchers still don't know what triggers an egg to split making two embryos from one fertilized egg.
What is the difference between dizygotic twins and monozygotic twins?
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
What is it call when twins are fertilized into two separate cells?
Dizygotic twins. If they were fertilized in the same egg, they would be called monozygotic twins.
How many egg cells are used with twins?
It depends on the type of twins If It was identical (monozygotic) twins, one egg is fertilized (As you can see, identical twins have similarity in phenotype (the observable characteristic of an organism) because of development of one zygote divided into two embryos) but if it was non-identical twins, two eggs or more (such as triplets or quadruplets) are fertilized. The twins have differences in phenotype
Why ate identical twins not clones?
because they fertilized egg split so they have the same DNA
My husband's grandmother was a twinWhat is the chance of me having twins?
The mans family history has nothing to do with twins or no twins....twins occur when a) the woman releases two mature eggs and they both get fertilized by two sperm or b) one mature egg is fertilized by one sperm and then that fertilized egg splits. One thing the man does contribute is the sex of the baby. A babies sex is solely determined by the father....not the mother.
What is the difference fraternal and identical twins?
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
