Is gayness hereditary

Answer 1

Special Genetic CasesYes: Although very rare, it is possible for a person to have XX chromosomes, but due to particular genetic factors, become a man. Similarly, it is possible for a person to have XY chromosomes but become a woman; however, such women tend to be unable or less likely to reproduce.

Other even more rare occurrences include the super sexes, where there are multiple sex determination chromosomes inside a person, eg XYY, XXY. or XXX.

This does not necessarily mean that all people born with these sets of chromosomes are gay or become gay. Furthermore, not all gay people are necessarily genetically gay this way.

Mixed sex twinsNo: When twins are born and one is male and the other female, sometimes testosterone from the male affects the development of the female embryo, who then has a stronger chance to be a lesbian. In this case, the gayness is not hereditary, but developed in the embryo. OtherFor most gays who do not fit either of the above criteria, whether or not their gayness is hereditary or partially hereditary is unknown at this point, with many theories abound.
