Biodiversity Research Seminar Series (BRS)

BRS: Stephen Wright "Y degenerate? Evolutionary genomics of plant sex chromosomes”

November 4, 2020, 12:00 pm to 1:00 pm

2212 Main Mall

host: Keith Adams

Abstract: Classical models suggest that recombination rates on sex chromosomes evolve in a stepwise manner to localize sexually antagonistic variants in the sex in which they are beneficial, thereby lowering rates of recombination between X and Y chromosomes. We investigated this prediction in the plant Rumex hastatulus, where a recent origin of a neo-sex chromosome allows for an explicit examination of the evolution of recombination rates before and after sex linkage. Our findings suggest that ancestrally low rates of recombination may facilitate the formation and subsequent evolution of heteromorphic sex chromosomes.
