The Y chromosome is well known to look for the sex that is male. What exactly is less distinguished: often 90 per cent for the Y chromosome consist of junk DNA that outcompetes elements that are functional. Inside the ERC task, biologist Qi Zhou investigates exactly exactly how it survived selection that is natural what effect it might probably have in the genome.
“The XY chromosomes mark the main differences that are genetic male and female”, describes Qi Zhou. “In animals, the Y chromosome determines a man intercourse.” The biologist happens to be learning intercourse chromosomes their whole job, but there are still numerous puzzling concerns that modern research cannot provide responses for – at the very least maybe perhaps not yet.
Learning good fresh good fresh fresh fruit flies
Zhou examines Drosophila, better referred to as fresh good fresh 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 yrs old. The machine that we make use of – Drosophila Miranda – is one million years old, and so I still find traces to study”, describes the ERC grantee through the University of Vienna. (more…)
