Identical twins are formed by the human egg splitting after being fertilized. The DNA also splits, and each new egg contains the DNA of the original. This means that the twins, once born, have identical DNA. It's worth nothing that they won't have the same physical fingerprint.

What would distinguish even an identical twin from its sibling?
Fingerprints are different in identical twins.
Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
What does fraternal twins and identical twins have in common?
Identical twins are twins that develop from same egg. These twins have same genome, also they have same physical appearance with minimal differences.
If a set of identical twins married another set of identical twins and each had a child would those children show up as siblings on a DNA test?
A standard DNA test would rank them as siblings.
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.
In what situations would DNA fingerprinting not be an appropiate tool for identification?
If you have two suspects who are identical twins, and you are trying to find out which one is the killer. Identical twins have identical DNA. However, identical twins do not have identical fingerprints, so you could just get a regular fingerprint sample instead.
Why identical twins are similar?
If they were not then they would not be called identical twins!
Who would have the most genetic similarities identical twins or fraternal twins?
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.
What is it called when one ovum is fertilized by one sperm and then splits to form two?
This is called monozygotic or identical twinning. It occurs when a fertilized egg (zygote) splits into two separate embryos, each with the same genetic material. These twins are often referred to as identical twins because they share the same DNA.
Would the Roloff twins be identical twins?
No, the Roloff twins (Jeremy and Zachary) are not identical. As the Roloff's point out, Jeremy is average height, and Zach is a little person.
If identical twins married identical twins could at least some of their kids look like twins?
Acctually, they're children would not look like twins. But all of their children would look like brothers and sisters.
What would distinguish even an identical twin from its sibling?
Fingerprints are different in identical twins.
Would You are two identical twins in identical dresses you sleep by day and live by night what are you?
Would and You are Chineese vampires
If Semi identical twins take paternity test what would the results be?
There is no such thing as "semi-identical" twins. If fraternal twins each take a paternity test, only the real father would show up as the father.
Can Tay-Sachs occur in twins?
Yes, it is possible. It would be more common if the twins are fraternal that only one twin would be affected by the disease because it is a recessive trait, meaning both parents must be a carrier for the offspring to be affected. If the twins are identical and the tay-sachs gene is present, then boths twins will be infected because identical twins have identical DNA
Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
What is the Differences between identical and nonidentical twins?
Identical twins are born together, and look exactly alike.Nonidentical twins are born together, but do not look exactly alike.A good example of non identical would be boy and girl twins,
