In a certain insect species, the females possess 32 chromosomes in their somatic cells while the males possess 16 chromosomes. The males develop from unfertilized eggs and produce gametes by mitosis. Which of the following terms correctly identifies this specific mechanism of sex determination?

Step-by-step solution

The scenario describes a system where females are diploid (32 chromosomes) and males are haploid (16 chromosomes). Since males develop from unfertilized eggs, they are haploid and must produce gametes by mitosis to maintain the chromosome number. This mechanism, where sex is determined by the number of sets of chromosomes an individual receives, is called the haplodiploid sex-determination system. The XX-XO type is found in grasshoppers, where males have one less chromosome than females but both are diploid. The ZZ
