Answer 2

Identical twins share the same DNA and blood type.

Step-by-step explanation:

It has been proven true by researchers of identical twins that identical twins share the same DNA and blood type because they develop from the same egg and sperm, also known as one zygote.

Unlike fraternal twins, which develop from two different eggs and sperms, identical twins share same DNA as they are monozygotic and difference in DNA structure is very rare.
