The Y chromosome is well known to look for the male intercourse. What exactly is less distinguished: frequently 90 % associated with Y chromosome is composed of junk DNA that outcompetes practical elements. Inside the ERC task, biologist Qi Zhou investigates exactly exactly how it survived selection that is natural what effect it could have from the genome.
«The XY chromosomes mark the main differences that are genetic male and female», describes Qi Zhou. «In mammals, the Y chromosome determines the male intercourse.» The biologist is learning intercourse chromosomes their whole profession, but you may still find numerous puzzling concerns that modern research cannot provide responses for – at the least perhaps maybe maybe not yet.
Learning fresh 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 significantly younger. » Our human Y chromosome is 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. […]
