Identical twins are formed from one fertilized egg, but fraternal twins form from two different fertilized eggs. Apply your knowledge of mitosis and meiosis to explain the genetic differences between identical and fraternal twins.

Identical twins share the exact same DNA while fraternal twins do not.

Explanation:

Mitosis is the type of cell division that results in 2 individual cells that have the exact genetic material.

Meiosis is the division of reproductive cells, eggs and sperms, which results in new cells with half the amount of genetic material and that makes them unique.

Identical twins are twins developed from a single egg that has been fertilized with a single sperm, meaning they have the same DNA.

Fraternal twins are twins from two different eggs that have been fertilized by two different sperms and grow in the womb at the same time with no additional cell division. So they have different DNA's.

I hope this answer helps.
