Document Summary
Mating is sexual union btwn ind that involves repro of two sexes, transmission of genetic info: genetic info contained in gametes form male donor to female, union=fertilization. In honeybees, eggs that dev into females do so after the union of sperm and egg nuclei in the egg, but males dev parthenogenetically from unfertilized eggs (arrhenotoky or haplo-diploidy) Honeybees used polyandry (multiple mating), system where females have several mating partners, offspring have diff fathers lol. Fem part of fam in honeybee colony are sisters and half-sisters: drones she mates with aren"t form her colony b/c bro-sis mating is not good in nature, products of the rare bro-sis mating are sterile. Queen enclose din cell and 5-10 days to mature to readiness to mate: orientation flights, becomes familiar w/ surroundings then goes to drone congregation areas where mating occurs. 6 to 8 days old, adult drones fly to congregation areas (km from hive), ready to mate when about 12-14 days olds.
