We’re taking time to get to know the members of the GSA’s Early Career Scientist Committees. Join us to learn more about our 2020 early career scientist advocates. Balint Z. Kacsoh  Policy Subcommittee  Epigenetics Department, University of Pennsylvania  Career Stage: Postdoc  Research Interest I believe that the interplay of neurobiology and the social sciences, termed “sociogenetics,” […]

Natural environments are seldom static and therefore it is important to ask how a population adapts in a changing environment. We consider a finite, diploid population evolving in a periodically changing environment and study how the fixation probability of a rare mutant depends on its dominance coefficient and the rate of environmental change. We find that, in slowly changing environments, the effect of dominance is the same as in the static environment, that is, if...

Chromosomal inversion polymorphisms have special importance in the Anopheles gambiae complex of malaria vector mosquitoes, due to their role in local adaptation and range expansion. The study of inversions in natural populations is reliant on polytene chromosome analysis by expert cytogeneticists, a process that is limited by the rarity of trained specialists, low throughput, and restrictive sampling requirements. To overcome this barrier, we ascertained tag single nucleotide polymorphisms (SNPs) that are highly correlated with inversion...
