No evidence for gay gene

We apologize, this video has expired. As Covid vaccines are shipped, experts appear divided on…. When the team looked more broadly across all the genomes — across the thousands of genes that they screened for the nearly , subjects — the genes similarities they found could only account for 8 to 25 percent of same-sex sexual behavior. Asked why they had wanted to conduct such research, the team told reporters on a teleconference that previous studies on this topic had mostly been too small to offer robust conclusions. Such behaviors emerge from constellations of hundreds, perhaps thousands, of genes, and how they are regulated by the environment. One gene cropped up for females and two others showed solid patterns in both males and females. Biobank and saliva samples from customers of the U.

She is a former staff reporter at Nature , New Scientist and Science and has a master's degree in molecular biology. Most participants came from the U. However, biologists have documented homosexual behavior in more than species , arguing that same-sex behavior is not an unnatural choice, and may in fact play a vital role within populations. Nonetheless, misconceptions persist that same-sex attraction is a choice that warrants condemnation or conversion , and leads to discrimination and persecution.
