DNA sequence response to experimental evolution at different sexual selection conditions
We have been maintaining Drosophila pseudoobscura populations in two regimes of high and low sexual selection for 150 generations. Several phenotypes have responded to selection during this limited time, for example courtship behaviour, morphology, fecundity and chemical communication.
We conducted RAD sequencing of 4 biological replicates of each condition and obtained >7000 regions containing SNP variation. We characterise the genes and genomic regions associated with consistent differences in SNPs between the selection regimes. We also comment on the repeatability of the response, with comparisons within each biological replicate.
