To be able to gain further understanding of the way the sex chromosomes work and just how they evolved.

The Y chromosome is well known to determine the male intercourse. What’s less distinguished: frequently 90 % of this Y chromosome is comprised of junk DNA that outcompetes elements that are functional. Inside the ERC task, biologist Qi Zhou investigates just how it survived selection that is natural what effect it might probably have in the genome.

“The XY chromosomes mark the main genetic differences when considering male and female”, describes Qi Zhou. “In animals, the Y chromosome determines a man intercourse.” The biologist was learning sex chromosomes their whole profession, but you can still find numerous puzzling concerns that modern research cannot provide responses for – at the least maybe perhaps maybe not yet.

Learning good fresh good fresh fruit flies

Zhou examines Drosophila, better referred to as good fresh good fresh fruit flies. Drosophila and people share the XY system, although the Drosophila’s Y chromosome is a lot younger. ” Our Y that is human chromosome about 180 million years of age. Weiterlesen
