Step-by-step solution
In grasshoppers, the sex determination is of the XX-XO type. The male is XO and produces two types of sperms: half with an X chromosome and half without any sex chromosome (A-IV). In birds like the domestic fowl, sex determination is of the ZZ-ZW type. The female is heterogametic (ZW) and produces two types of eggs: one with a Z chromosome and one with a W chromosome (B-III). In Drosophila, sex determination is of the XX-XY type. The male is heterogametic (XY) and produces two types of sperms: one with an X chromos
