Sex determination in honey bees is initially due to a single locus, called the complementary sex determiner ( csd) gene. In developing bees, if the conditions are that the individual is heterozygous for the csd gene, they will develop into females. See more Haplodiploidy is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. Haplodiploidy is sometimes called See more Several models have been proposed for the genetic mechanisms of haplodiploid sex-determination. The model most commonly referred to is the complementary allele model. According to this model, if an individual is heterozygous for a certain See more • Green-beard effect • Ploidy • Pseudo-arrhenotoky • Sexual differentiation See more Relatedness is used to calculate the strength of kin selection (via Hamilton's rule).
