Varroa routinely inbreed so in addition to having a short "cycle time"
so to speak, they're particularly good at propagating "favorable"
traits. Foundress mites typically enter singly into cells to breed. Only
when 2 or more foundress mites enter a cell do their daughters have a
chance of mating with males other than their own brothers.
