Strikingly high levels of heterozygosity despite 20 years of inbreeding in a clonal honey bee

We assessed the extent to which heterozygosity is important to the genetic architecture of honey bees, and potentially to insects more broadly. We aim to explain the pervasiveness of heterozygosity within the honey bee genome and assess the extent to which heterozygote-advantage has shaped the genomic architecture of honey bees, and potentially to insects more broadly.
