Ever wondered what makes some alleles dominant (A) and others recessive (a) ?
In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...
Why do sex chromosomes stop recombining? New models show even weak sexual antagonism can strongly drive recombination suppression, with mating systems shaping the outcome. By @ewanflintham.bsky.social and @charlesmullon.bsky.social doi.org/10.1093/evle...
Thrilled that our new review article on animal hybridization is now up on EcoEvoRxiv! 🎉 Working on this review with @mollyschumer.bsky.social was a blast, and it was such a wonderful opportunity to catch up on all the amazing work in animal hybridization over the last few years!
