Our study on pleiotropy and evolution of a population of Arabidopsis thaliana recently got out.
Following a genetically diverse population of A. thaliana across a period of 10 years we observed evolution for many adaptive traits. Looking at the genetic basis of these traits, we identified numerous genomic regions with intermediate to high level of pleiotropy. Interestingly, and contrary to my expectations based on Fisher’s geometrical model, genetic regions with intermediate level of pleiotropy evolved the most in this population.
