Final answer:
Fraternal twins are formed from two separate eggs fertilized by different sperm cells, while identical twins are formed from a single fertilized egg that splits into two embryos. Fraternal twins share about 50% of their genetic material and can have different appearances, while identical twins share 100% of their genetic material and have a striking resemblance to each other.
Step-by-step explanation:
Difference between Fraternal and Identical Twins
Fraternal twins are formed when two separate eggs are fertilized by two different sperm cells. These twins are as similar as any siblings and can be of different genders. On the other hand, identical twins are formed when a single fertilized egg splits into two separate embryos. They have the same genetic material and are always of the same gender.
While fraternal twins share about 50% of their genetic material, just like any other siblings, identical twins share 100% of their genetic material. In terms of appearance, fraternal twins can look as similar or different as any other siblings, whereas identical twins have a striking resemblance to each other.
