Drones are produced from unfertilized eggs and therefore represent only the DNA of the queen that laid the eggs, i.e. have only a mother. Workers and queens result from fertilized eggs and therefore have both a mother and a father. A modified form of Parthenogenesis controls sex differentiation. The sex Allele is Polymorphic and so long as two different variants are present, a female bee results. If both sex alleles are identical, diploid drones are produced. Honeybees detect and destroy diploid drones after the eggs hatch.
Queens typically mate with multiple drones on more than one mating flight. Once mated, they lay eggs and fertilize them as needed from sperm stored in the Spermatheca. Since the number of sex alleles is limited - about 18 are known in Apis - there is a high probability that a queen will mate with one or more drones having sex alleles identical with one of the sex alleles in the queen. It is therefore typical for a queen to produce a percentage of diploid drone eggs.
[edit]Micrapis
Apis florea and Apis andreniformis are small honey bees of southern and southeastern Asia. They make very small, exposed nests in trees and shrubs. Their stings are often incapable of penetrating human skin, so the hive and swarms can be handled with minimal protection. They occur largely sympatrically though they are very distinct evolutionarily and are probably the result of allopatric speciation, their distribution later converging. Given that A. florea is more widely distributed and A. andreniformis is considerably more aggressive, honey is – if at all – usually harvested from the former only. They are the most ancient extant lineage of honey bees, maybe diverging in the Bartonian (some 40 million years ago or slightly later) from the other lineages, but among themselves do not seem to have diverged a long time before the Neogene.[4]
[edit]Megapis
There is one recognised species in subgenus Megapis. It usually builds single or a few exposed combs on high tree limbs, on cliffs, and sometimes on buildings. They can be very fierce. Periodically robbed of their honey by human "honey hunters", colonies are easily capable of stinging a human being to death when provoked.

Apis dorsata on comb
Apis dorsata, the giant honey bee, is native and widespread across most of South and Southeast Asia.
Apis dorsata binghami, the Indonesian honey bee, is classified as the Indonesian subspecies of the giant honey bee or a distinct species; in the latter case, A. d. breviligula and/or other lineages would probably also have to be considered species.[5]
