Some 300 million years back, the ancestor that is living of had been a reptile. Like turtles and alligators today, it allow the heat of which its eggs were incubated decide their intercourse.

wild Birds and animals, two groups that descended through the reptiles, put sex underneath the more control that is reliable of, maybe not of heat. But sex-determining genes pose a problem that is severe the business of the genome. In a few experiments within the last 15 years, David Page associated with Whitehead Institute has reconstructed most of the actions into the development regarding the peoples intercourse chromosomes, which he calls “an infinitely rich test of nature.” He’s got now began to evaluate a synchronous test, the intercourse chromosomes of birds.

In people, males have actually an X and a Y chromosome, and females two X’s. Continue reading “Wild Wild Birds Chose path that is different Manage Their Sexes”
