When sperm and egg unite, they create a zygote through fertilization. Over time, the zygote will divide into millions upon millions of cells. Each cell consists of 46 chromosomes; these cells, as a whole, will become the baby. However, the process is not the same for every situation and some things can go differently.
Monozygotic twins, also known as identical twins, come from a single zygote. During the process stated above, the zygote for whatever reason splits into two separate entities and eventually they will become the babies. The babies will be identical in nature (same sex and same physical features for the most part). This occurs because they each contain the same set of 46 chromosomes deriving from the single zygote.

∙ 16y agoIdentical twins occur when a single fertilized egg splits into 2. It's considered to be a random anomoly - so nobody really knows why the egg decides to split.

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 type of twins share the greatest genetic overlap?
Monozygotic twins.
Why are some twins identical and some not?
The reason why some twins are identical and some are not starts in utero. Identical twins occur when one egg is fertilized and it splits to create two embryos. Nonidentical twins come from different fertilized eggs.
Why are twins formed in one embryo?
Identical twins are sometimes formed when one egg after being fertilized by one sperm, divides into two halves.
Why are identical twins identical and fraternal twins are not?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
What is the Medical term meaning identical twin?
monozygotic or maternal twins
What is the difference between dizygotic twins and monozygotic twins?

What is another name for maternal twins?
Monozygotic Twins
Are monozygotic twins opposite sex?
No, monozygotic twins would be the same sex. Monozygotic twins come from one single fertilized egg, or zygote, which then splits to create two separate zygotes which will be genetically identical, or "identical twins", which will always be of the same gender.
Are John and Edward Grimes twins?
Yes they are twins. They are monozygotic twins (identical twins).
What type of twins have the greatest similarity in IQ?
MonoZygotic Twins
What is the frequency of monozygotic twins versus dizygotic twins?
The frequency of having monozygotic twins (identcal) is about 4 out of every 1000 births. Whereas dizygotic twins (fraternal) is about 12 out of every 1000.
Twins who delevelop in separate amniotic sacs?
They are called: fraternal or dizygotic twins. Twins who develop in one amniotic sac are called identical or monozygotic twins.
What type of twins share the greatest genetic overlap?
Monozygotic twins.
Does identical twins have to run in the family?
monozygotic twins do not run in families
Identical twins are also referred to as?
Monozygotic
Whom are considered monozygotic twins?
Monozygotic twins are also known as identical twins. They form from a single egg that splits into two forming two babies with the same genetic information.
