新研究發現與人類雙性戀行為相關的遺傳變異

New Research from LA Blades Chart and University of Michigan: Exploring the Genetic Basis of Bisexual Behavior

在最近的一項研究中，密西根大學的研究人員揭示了與人類雙性戀行為相關的遺傳變異，這項研究不僅為我們提供了對性行為多樣性的深入理解，也挑戰了長期以來對於性取向的一些偏見和誤解。

The study, published Jan. 3 in the journal Science Advances and led by University of Michigan professor Jianzhi Zhang and graduate student Siliang Song, analyzed genetic and health information from more than 450,000 European ancestry participants. The participants, all of whom came from the U.K. BioBank database, answered questions including "Would you describe yourself as a risk taker?" They answered questions including "Would you describe yourself as an adventurous person?

The results of the study show that male heterosexuals who carry a genetic variant associated with bisexual behavior (i.e., the BSB-related allele) have a higher-than-average number of children. This finding may at least partially answer a long-standing question in evolutionary biology: how genes associated with same-sex behavior persist in humans.

In addition, the researchers found that men who described themselves as adventurous tended to have more children and were more likely to carry BSB-related alleles. This result suggests that genetic traits associated with bisexuality are also associated with male risk-taking behavior.

Notably, the researchers emphasized that their study focused on the genetic basis of same-sex sexual behavior rather than the behavior itself, which is influenced by both genetic and environmental factors. They estimate that a person's bisexual behavior is influenced by about 401 TP3T by genetic factors and about 601 TP3T by environmental factors.

The findings of this study not only help us better understand the diversity and richness of human sexuality, but also emphasize the role that scientific research can play in eliminating discrimination against sexual minorities. The researchers state that they do not intend to imply or support discrimination on the basis of sexual behavior in any way.

However, an article in the journal Science noted that reaction to the study has been mixed, with some scientists and experts questioning its reliance on data from the UK Biobanking Survey, and others expressing concern about its claim that bisexual-related adventures may perpetuate prejudice against bisexuals and gays.

Nonetheless, this study undoubtedly provides valuable insights into the issue of bisexuality and exclusive same-sex behavior, and offers new perspectives on our understanding of genetic and environmental factors in sexual orientation. With the increasing acceptance of same-sex behavior in our society, this type of research will continue to play an important role in promoting the understanding and acceptance of sexual diversity.
