In the haplodiploid sex-determination system, what is unique about the male honey bee's lineage?

Options

  1. AMales have no grandfathers
  2. BMales have no fathers
  3. CMales have no grandsons
  4. DMales can have sons

Correct answer

B. Males have no fathers

Step-by-step solution

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 unfertilised egg develops as a male (drone) by means of parthenogenesis. This means that the males have half the number of chromosomes than that of a female. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called as haplodiploid sex-determination system
