Balancing selection
Balancing selection maintains advantageous diversity in populations by a variety of mechanisms. In humans it is responsible, for example, for the extreme levels of genetic diversity of the MHC locus, and for the fascinating equilibrium that maintains sickle-cell anemia alleles in malaria-suffering populations due to heterozygotes advantage. In other species, balancing selection maintains diversity that is crucial for sex determination, self-incompatibility, defense against pathogens, or escape from predators. Our goal is to understand the influence of balancing selection in the genome (its prevalence, conservation among populations and species, its most common targets) and to unravel the biological factors behind its signatures (its specific targets, the functional consequences of selected variants, their contribution to phenotypic diversity in populations). For this, we combine genomic approaches with detailed population genetics, computational, and experimental studies, that allow us to go from the genome to the phenotype.
