Washington: Researchers led by one of Indian origin have uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern quite a few particular type of male and female behaviours in mice.Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviours that separate men from women.A team of scientists at the University of California, San Francisco (UCSF) selectively turned many of these genes off one by one and found they could manipulate individual behaviours in the mice, like their sex drive, desire to pick fights, or willingness to spend extra time caring for their young.“It’s as if you can deconstruct a social behavior into genetic components,” said Nirao Shah, MD, PhD, an associate professor in the Department of Anatomy at UCSF who led the research.“Each gene regulates a few components of a behavior without affecting other aspects of male and female behavior.
