Describe Haplodiploid sex determination system in Honey Bees.

Explanation

(a) This type of sex-determination is seen in honeybees: it is based on the number of sets of chromosomes, an individual receives. (c) When the ocum develops by pathenogenesis, i.e., without fertlisation a male individual, called drone, is formed.
(d) The male honey bee (drone) is haploid (with n=16 chromosomes) and forms sperms by mitosis.
(e) The sex-determination is as follows:

(f) The special characteristic features of this system of sex-determination are:
* The male honey bees do not have a father, but have a grandfather.
* They do not have sons, but can have grandsons.
