To be able to gain insight that is further the way the intercourse chromosomes work and how they developed.

The Y chromosome is well known to determine the sex that is male. What exactly is less distinguished: often 90 % regarding the Y chromosome is made from junk DNA that outcompetes practical elements. In the ERC task, biologist Qi Zhou investigates just just exactly how it survived normal selection and what effect it could have from the genome.

“The XY chromosomes mark the most important genetic differences when considering male and female”, describes Qi Zhou. “In animals, the Y chromosome determines the male intercourse.” The biologist is learning intercourse chromosomes their whole job, but you can still find numerous puzzling questions that modern research cannot provide responses for – at the very least maybe maybe not yet.

Learning fresh 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 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. Continue reading
