Fraternal twins, or dizygotic twins, form when two separate eggs are fertilized by two different sperm cells during the same menstrual cycle. This results in two genetically unique siblings who share about 50% of their DNA, similar to regular siblings. Fraternal twins can be of the same sex or different sexes and may or may not look alike. Factors such as maternal age, genetics, and the use of fertility treatments can influence the likelihood of having fraternal twins.
