The Y chromosome is well known to look for the male intercourse. What exactly is less well known: frequently 90 per cent associated with the Y chromosome is comprised of junk DNA that outcompetes practical elements. In his ERC task, biologist Qi Zhou investigates exactly just just how it survived normal selection and what effect it might probably have in the genome.

“The XY chromosomes mark the most important differences that are genetic male and female”, describes Qi Zhou. “In animals, the Y chromosome determines the male intercourse.” The biologist happens to be learning intercourse chromosomes their entire profession, but you may still find numerous puzzling concerns that modern research cannot provide responses for – at the least maybe maybe not yet.

Learning fresh good fresh fruit flies

Zhou examines Drosophila, better referred to as good fresh good fresh good fresh fruit flies. Drosophila and people share the XY system, although the Drosophila’s Y chromosome is a lot younger. ” Our peoples Y chromosome is about 180 million years of age. The device so I still find traces to study”, explains the ERC grantee from the University of Vienna that I work with – Drosophila Miranda – is only one million years old.

Human Genome Venture

We have to go back to the 1990s: An international board of over 50 scientists from all over the world collaborated on the Human Genome Project if we are to understand what makes the Y chromosome so special. The aim of the task would be to figure out the series of nucleotide base pairs that form the DNA that is human. ” when you look at the world that is biological can be simply when compared with Apollo 13″, smiles Zhou.
