Question

What is the difference between fraternal and identical twins

Answer 1

Fraternal: they don't look alike

Identical: do look alike

Step-by-step explanation:

Identical twins are called monozygotic twins.

Fraternal twins are called dizygotic twins.

Answer 2

The main difference between fraternal and identical twins is how they are formed. Fraternal twins are formed when two separate eggs are fertilized by two separate sperm. As a result, fraternal twins are not genetically identical and can be of different sexes.

On the other hand, identical twins are formed when a single fertilized egg splits into two embryos. As a result, identical twins are genetically identical and are always of the same sex.

There are also some physical differences between fraternal and identical twins. Identical twins tend to look very similar, with the same eye color, hair color, and facial features. Fraternal twins, on the other hand, may look more similar to each other than to other siblings, but they are not identical.

Overall, the main difference between fraternal and identical twins is how they are formed and their genetic makeup.
