Title:

Muller's ratchet and the incredible shrinking Y-chromosome

Date: Thursday, May 8, 2003

Time: 2:30 - 3:20pm

Place: Guggenheim Room AMATH Library


Abstract. Geneticists since Fischer have argued over the adaptive value of recombination. It is now understood that recombination saves genomes from the accumulation of deleterious mutations known as Muller's ratchet. However, in species which select gender via X/Y chromosomes, a large portion of the Y-chromosome does not undergo recombination, and should gradually accumulate deleterious mutations. I will be examining whether a very simple model can estimate the "rate of decay" of the Y-chromosome.
