Document Summary
Unit six honey bee adaptation and diversity: races, strains, and. The term race when referring to honey bees is used as synonym of subspecies, whereas strain is a bee genotype within a subspecies. The following is an outline of key information about this subtopic. There is controversy as to where honey bees originated. The fact that most species of true honey bees are widespread in southern asia, suggests an asiatic origin, but a genomic study points towards an african origin. More evidence is needed from future studies to gain insight about the region of origin of apis mellifera. Today, a. mellifera populations are distributed across the world. Subspecies or races are a taxonomic rank below that of species. Races are genetically distinct populations of individuals that interbreed within the same species. Chihuahua dogs look very different, but both belong to the same species, canis familiaris. Therefore, even when unlikely, they could mate and produce progeny.
