Solution
In certain insects, such as crickets, grasshoppers, and others, the homogametic sex is female, and they possess two X chromosomes (XX). The male is the heterogametic sex and only carries one sex chromosome. In XX-XO systems, males produce gametes containing either an X chromosome or no sex chromosome (O).
