Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy. They share half of their genes, just like any other siblings. Fraternal twins can be of the same or different sexes.

Brotherly Love

Incestuous twin brothers wonder if they should reveal their secret relationship.

When Billie Ozturk walks down the street with her twin sister Jasmine Reynolds they regularly receive unsolicited sexualised comments. Often the sisters feel social pressure to laugh such comments off; but underneath they find them hard to deal with. While most adults are considered autonomous individuals, twins are regularly treated as two halves of a whole. In short : they become a package deal. Once a man even offered to pay us. When Love Island producers selected year-old twins Jess and Eve Gale for the line-up they were playing into long-established ideas about twin sisters.

Are there more same-sex SS than opposite-sex OS pairs among dizygotic twins? However, recent research on the sex-specific nature of breastmilk suggests that OS twins might be at a developmental disadvantage relative to SS twins. There may therefore be evolutionary selection for the tendency to have SS twins and against the tendency to have OS twins. We performed a one-sample t -test of the proportion of SS dizygotic twins against the theoretical null value of 0.
