Vedclass · Answer

(B) In many insects like grasshoppers,sex determination follows the $XO$ type. In this mechanism,males have only one $X$ chromosome (they are $XO$),while females have a pair of $X$ chromosomes $(XX)$.However,in honeybees,sex determination is based on the number of sets of chromosomes (haplodiploidy). Females (queens and workers) are diploid $(2n = 32)$,and males (drones) are haploid $(n = 16)$.Since honeybees do not possess specific sex chromosomes to determine sex,but rather rely on ploidy levels,they do not have a 'sex chromosome pair' in the traditional sense compared to $XX/XY$ or $XX/XO$ systems.Therefore,the queen honeybee does not have a specific pair of sex chromosomes that determines her sex; rather,her sex is determined by her diploid state.

In which of the following organisms are sex chromosome pairs $NOT$ found?
