A fertilized egg splits in two- Apex
yes they are... simmes twins form from one egg that is in the process of separating into two eggs or identical twins... but the process isn't finished and that is why they are "stuck together"
Approximately 30 of twins are identical, also known as monozygotic twins.
Non identical twins.
No, identical twins do not always share a placenta. In some cases, identical twins may have separate placentas.
The percentage of identical twins in the world is approximately 0.2.
Identical twins develop from a single zygote that splits into two embryos during early development. Therefore, only one zygote is needed to form identical twins.

Non-identical twins are when 2 sperm cells fertilize two different eggs during the same pregnancy.
Identical twins are formed when a fertilized egg splits in two and separates, creating two embryos. Fraternal twins form when two separate eggs are fertilized.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
If they were not then they would not be called identical twins!
Identical twins form when an egg is released from the ovary and is fertilised by a sperm and then splits into two. They then form naturally. Non-identical twins form when two eggs are released from the ovary and then fertilised by a sperm. They also form naturally. Identical twins have to be of the same sex (two boys or two girls) because they have come from the same egg which contains the same DNA. Non-identical twins can be either boy and girl or of the same sex (two boys or two girls) because they came from two different eggs and so have two different sets of DNA.

Twins are identical because they come from the same egg.
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.
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
The same as when you had the first set of identical twins.
