Identical Twins
Twins who originate from a single fertilized egg that splits into two, sharing 100% of their genetic material.
Single Egg Cell
The female gamete or ovum, which, when fertilized by a sperm, results in the development of an embryo.

Final Answer :
A
Explanation :
Identical twins, also known as monozygotic twins, come from a single fertilized egg cell (zygote) that splits into two separate embryos. Therefore, they have the same genetic material because they come from the same zygote.
