Monserrat Petty · Answer 1

The correct answer is 50%

Explanation:

Fraternal twins are the twins which are produced from the fertilization of two different eggs by two different sperms. These eggs are released at the same time.

So as fraternal twins are produced from fertilization of two different eggs therefore they share 50% of genes with each other just like other siblings. They are also called dizygotic twins

Identical twins are produce from a sigle fertilized cell which later divides into two cell mass. Indentical twins share 100% gene. Therefore the correct answer is 50%.
