SALT LAKE CITY, Dec. 17, 2015 - A University of Utah-led study identified a long-sought "hybrid inviability gene" responsible for dead or infertile offspring when two species of fruit flies mate with each other. The discovery sheds light on the genetic and molecular process leading to formation of new species, and may provide clues to how cancer develops.
"We knew for decades that something like this gene ought to exist, and our approach finally allowed us to identify it," says biologist Nitin Phadnis, principal author of the study published today in the journal Science.
The definition of a species is that it cannot breed successfully with another species, so "to understand speciation is to understand how these reproductive barriers evolved,"READ MORE -http://www.eurekalert.org/pub_releases/2015-12/uou-agf121115.php
