Final answer:
The haplodiploid system of sex determination is characteristic of bees and ants, where males are haploid and females are diploid. Grasshoppers and sharks do not utilize this system; grasshoppers use the XY system, and sharks have different methods.
Step-by-step explanation:
The haplodiploid system of sex determination is found in certain insects, such as bees and ants. In these insects, males are haploid because they develop from unfertilized eggs, while females are diploid as they develop from fertilized eggs. This system is distinct from the XY and ZW sex-determination systems, which are found in other animals. For example, the XY system is present in mammals and some insects and plants, whereas the ZW system is utilized by birds, some fish, crustaceans, insects (like butterflies and moths), and reptiles. Grasshoppers use the XY system of sex determination, and sharks also have their own sex determination systems.
