How could a guinea pig breeder whether a rough-coated guinea pig is homozygous or heteorzygous for this trait?

A breeder could determine if a rough-coated guinea pig is homozygous or heterozygous by conducting a test mating. Breeding the rough-coated guinea pig with a smooth-coated guinea pig would show if the rough coat is dominant or recessive. If all the offspring have rough coats, it indicates the rough-coated guinea pig is homozygous for the trait. If both rough and smooth-coated offspring are produced, then the rough-coated guinea pig is heterozygous.
