Fraternal twins or dizygotic twins happen when two different eggs are fertilized by two sperm. In spite of the etymology fraternal twins need not be male or even of the same sex. They generally share about 50 percent of their genes.

Fraternal twins are dizygotic meaning that they developed from two different eggs fertilized by two different sperms. Paternal and fraternal twins are also known as monozygotic and dizygotic twins. Non-identical twins produced by the simultaneous fertilization of two different eggs by different sperms dizygotic twins. Sometimes the differences are so subtle that only close friends and relatives can spot them.
