===Genetic basis===
Researchers found that disabling the fucose mutarotase<ref>{{cite web | url=http://www.wikigenes.org/e/gene/e/945842.html | archive-url=https://web.archive.org/web/20160610084742/http://www.wikigenes.org/e/gene/e/945842.html | archive-date=10 June 2016 | title=WikiGenes - Collaborative Publishing }}</ref> (FucM) gene in laboratory mice – which influences the levels of [[estrogen]] to which the brain is exposed – caused the female mice to behave as if they were male as they grew up. "The [[Knockout mouse|mutant female mouse]] underwent a slightly altered developmental programme in the brain to resemble the male brain in terms of sexual preference" said professor Chankyu Park of the [[Korea Advanced Institute of Science and Technology]] in Daejon, South Korea, who led the research. His findings were published in the [[BioMed Central|''BMC Genetics'' journal]] on July 7, 2010.<ref>{{cite news|url=https://www.telegraph.co.uk/science/science-news/7877774/Female-mice-can-be-turned-lesbian-by-deleting-gene.html |archive-url=https://web.archive.org/web/20100710155012/http://www.telegraph.co.uk/science/science-news/7877774/Female-mice-can-be-turned-lesbian-by-deleting-gene.html |url-status=dead |archive-date=2010-07-10 |title=Female mice 'can be turned lesbian by deleting gene' |newspaper=The Telegraph |date=2010-07-08 |access-date=2010-11-17 |location=London |first=Matthew |last=Moore| name-list-style = vanc }}</ref><ref>{{cite journal | vauthors = Park D, Choi D, Lee J, Lim DS, Park C | title = Male-like sexual behavior of female mouse lacking fucose mutarotase | journal = BMC Genetics | volume = 11 | pages = 62 | date = July 2010 | pmid = 20609214 | pmc = 2912782 | doi = 10.1186/1471-2156-11-62 | publisher = BioMed Central | doi-access = free }}</ref> Another study found that by manipulating a gene in fruit flies (''[[Drosophila]]''), homosexual behavior appeared to have been induced. However, in addition to homosexual behavior, several abnormal behaviors were also exhibited apparently due to this mutation.<ref>{{cite journal| vauthors = Terry J |title='Unnatural Acts' in Nature: The Scientific Fascination with Queer Animals |journal=GLQ: A Journal of Lesbian and Gay Studies|year= 2000|volume=6|issue=2|pages=151–193|doi=10.1215/10642684-6-2-151|s2cid=145504677 }}</ref>
