Factors Related to Homosexuality
Homosexuality is mostly influenced by both genetics and environmental factors. According to researchers from Queen Mary’s School and Karolinska Institute in Stockholm, genetics and environmental factors which are specific to an individual (biological processes such as different hormone exposure in the womb) are the important determinants of homosexuality. Finding a single ‘gay gene’/ gene for heterosexual behaviour is influenced by a mixture of genetic and environmental factors, therefore it is very complicated.
The overall study proved that genetics accounted for around 35% of the differences between men in homosexual behaviour and other individual-specific environmental factors are accounted for 64%.
