The Y chromosome is famous to look for the male intercourse. What exactly is less distinguished: frequently 90 % of this Y chromosome is made from junk DNA that outcompetes practical elements. In the ERC task, biologist Qi Zhou investigates exactly exactly how it survived selection that is natural what effect it could have regarding the genome.

“The XY chromosomes mark the main 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 whole job, but you may still find numerous puzzling concerns that modern research cannot provide responses for – at the least perhaps maybe not yet.

Learning good fresh fruit flies

Zhou examines Drosophila, better referred to as fresh fruit flies. Drosophila and people share the XY system, although the Drosophila’s Y chromosome is significantly younger. ” Our Y that is human chromosome about 180 million years old. The machine 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. ” In the world that is biological can be easily when compared with Apollo 13″, smiles Zhou.
