Identical twins develop from one zygote, while fraternal develop from two different eggs
Do you happen to know any twins? I do not, do you and would they be fraternal twins? Fraternal twins are those who each got fertilized by a sperm cell. What is the difference between fraternal and identical?
Twins can be either ''monozygotic'' (''identical''), meaning that they develop from one zygote, which splits and forms two embryos, or ''dizygotic'' (''fraternal''), meaning that they develop from two different eggs.
