Men with “Bisexual Genes” Have More Children

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

Genes related 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 have an impact on risk taking and having more children. In the UK Biobank located and Genetic information of 450 thousand people The study conducted on the subject revealed this situation.

In the study developed based on a paper first published in a seminar in 2019, 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 behaviors were viewed the same, but homosexuality was more of a spectrum. Zhang and the study’s co-author, Silang Song, showed that the genes that lead to same-sex attraction and bisexual tendencies are different.

The complex balance of nature

According to research BSB (Bisexual behaviors) related alleles Heterosexual men who carry genes called are more likely to have more children. Thus, they can pass this gene on to the next generations. The authors argue that these people have a reproductive advantage, so these tendencies can continue to exist.

According to the study high risk taking behavior, triggers men carrying these alleles to have more unprotected sexual intercourse. This results in them having more children. Additionally, these people have more partners. It turns out that heterosexual men who carry genes that trigger same-sex attraction have fewer children.
