Australian researchers discover how a baby’s sex is determined

Sydney: While it is known that the sex of a baby is determined by its chromosome make-up at conception, new research has identified a “regulator” that increases or decreases the activity of genes which decide if we become male or female. “These regulatory segments of DNA are called enhancers,” said the lead author of the study Andrew Sinclair, Professor at the University of Melbourne in Australia.

“If these enhancers that control testis genes are disrupted it may lead to a baby being born with a disorder of sex development,” Sinclair said. (IANS)
