In the psychology context, fraternal twins refer to a type of twins that result from the fertilization of two separate eggs by two separate sperm. They are also known as dizygotic twins and are genetically no more alike than any other siblings.
Fraternal twins can be of the same or different genders, and they share, on average, 50% of their genetic material. Fraternal twins are more common than identical twins and occur in about 1 in 80 pregnancies.
Some examples of fraternal twins include:
- Mary-Kate and Ashley Olsen, American actresses and fashion designers
- Jenna and Barbara Bush, daughters of former US President George W. Bush
- Tia and Tamera Mowry, American actresses
- Vin Diesel and Paul Vincent, American actors and producers
- Joel and Benji Madden, American musicians and twin brothers of the band Good Charlotte.
Fraternal twins may share similar environments while growing up, but they are not necessarily more similar in personality or behavior than non-twin siblings.
