Question : Read the following statements and find out the correct statements. The sex determination in honey bee is based on the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker), and an unfertilized egg develops as a male (drone) by means of parthenogenesis. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called as haplo-diploid sex-determination system and has special characteristic features such as the males produce sperms by mitosis they do not have father and thus cannot have sons, but have a grandfather and can have grandsons.
