Identical twins are formed from one egg and one same sperm. After conception or fertilization, this cell should develop into one zygote. In identical twins, after the conception of the egg and sperm which are fused, it divides into two zygotes. Then the two new zygotes grow into two individuals. It’s because it comes from one egg and the same sperm, identical twins have the same DNA, from one egg cell to the mother and one sperm to the same father.

DNA (Deoxyribonucleate) consists of chromosomes that contain genetic information. This genetic information determines all the characteristics and characteristics of the body. Starting from the color of hair and eyes, muscle structure, and so forth.
Although identical twins, but apparently identical twins still have differences, right? Even though it’s only a little or maybe there are many differences. So this is the question, why do there still differ from one source of genetic information. Actually the DNA is the same or not?
Is it true that identical twin DNA is really identical too?
Reported on the Very well Fit page, DNA tests on identical twins or monozygotic twins will give 99.99% similar results. Whereas if the twins are not identical or fraternal twins are generally similar around 50-75 percent.
Quoted in the page of the National Human Genome Research Institute, namely a human gene research institute in America, Don Hadley, MS., C.G.C said that identical twins share the exact same DNA during the womb. However, changes can occur after fertilization, so this makes their DNA still different.
Therefore, it can be said that identical twins do not mean having identical DNA too, but the DNA is very similar.
The proof, you can see for yourself there is always a difference between identical twins. That is, DNA that carries their genetic information is not identical. Although the difference is only a little or you might find it difficult to distinguish, but basically there are different things.
For example, fingerprints can be similar but not 100 percent exact. In addition, for example, face shape or hair color. This is all because their DNA is not one hundred percent ine hundred percent identical, but very similar.
