The cytological observations made in a number of insects led to the development of the concept of genetic/chromosomal basis of sex-determination mechanism. Honey bee is an interesting example to study the mechanism of sex-determination. Study the schematic cross between the male and the female honey bees given below and answer the questions that follow:
 

(a) Identify the cell divisions ‘A’ and ‘B’ that lead to gamete formation in female and male honey bees respectively.
(b) Name the process ‘C’ that leads to the development of male honey bee (drone).
