from the University of Michigan Professor Jianzhi “George” Zhangwhich has been discussed for a long time in his new study,Why doesn’t natural selection eliminate the genes associated with homosexuality?” It may have answered your question. 450 thousand people According to a study using genetic information, heterosexual men with bisexual genes have more children.

Genes linked to bisexuality have been identified

For the first time in history, genetic variations related to bisexuality have been revealed. Scientists have revealed that if these variants are found in heterosexual men, they affect risk-taking and having more children. In the British Biobank located and Genetic information of 450 thousand people The investigation into this matter has revealed this situation.

In the research developed from an article first published at a 2019 seminar, genetic factors Although he says it can be effective environmental factors He said it was more important. Zhang also said that in the past, all homosexual behavior was viewed the same, but homosexuality was more of a spectrum. Zhang and the study’s co-author, Silang Song, showed that the genes leading to same-sex attraction and bisexual tendencies are different.

The complex balance of nature

According to research BSB (Bisexual behavior) related alleles Heterosexual men who are carriers of so-called genes have a greater chance of having more children. This way they can pass on this gene to the next generations. The authors argue that these people have a reproductive advantage so these tendencies can persist.

According to the study high-risk behavior, causes men who carry these alleles to have more unprotected intercourse. This means they have more children. Moreover, these people have more partners. It turns out that heterosexual men who carry genes that trigger same-sex attraction have fewer children.
