Honey bees have the highest meiotic recombination rate among multicellular organisms. Several hypotheses exist to explain why these extraordinarily high rates of chromosome exchanges happen in honey bees and some other social insects. However, we need more information to satisfactorily answer this question. We are interested in generating and analyzing genomic data from other species of honey bees and social insects to explore the link between high recombination rates and social evolution. In addition, we like to know how variable and environmentally responsive the recombination rate within the species Apis mellifera is. We complement these studies with efforts to elucidate the mechanisms of meiotic recombination in honey bees. Studying the mechanistic changes that allow the high rates of crossovers between honey bee chromosomes may allow us to better understand the process of meiotic recombination and its regulation in general, with potential human health implications.
