how does the genetic makeup of a fraternal and identical differ
Identical and fraternal twins typically share many similar characteristics
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.

Quads can be identical, fraternal, or a pair of identical twins. Identical quads are rare- that would require 1 egg divide into 2, and then divide again into two. Most quads are fraternal.
