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.

What happens when twins are formed from one embryo?
When twins are formed from one embryo, it is known as monozygotic twinning. This occurs when a single fertilized egg splits into two embryos. As a result, the twins will share the same genetic material, leading to identical or monozygotic twins.
What are the key differences between monozygotic and dizygotic twins in terms of their genetic makeup and development?
Monozygotic twins, also known as identical twins, are formed from a single fertilized egg and share the same genetic makeup. Dizygotic twins, or fraternal twins, are formed from two separate eggs fertilized by two different sperm cells, resulting in different genetic makeup. Monozygotic twins are more similar in terms of genetic traits and development compared to dizygotic twins.
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.
Do monozygotic twins share a placenta?
Yes, monozygotic twins can share a placenta if they implant close enough to each other in the uterus.
What percentage of twins are identical?
Approximately 30 of twins are identical, also known as monozygotic twins.

What is the Medical term meaning identical twin?
monozygotic or maternal twins
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.
Do monozygotic twins share a placenta?
Yes, monozygotic twins can share a placenta if they implant close enough to each other in the uterus.
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.
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.
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.
What percentage of twins are identical?
Approximately 30 of twins are identical, also known as monozygotic twins.
