Q.

what are the difference between outcrossing and crossbreeding ?

Q. In guinea pigs, short coat is dominant to long.
If a breeder wants to ensure that the short-haired guinea pig he has is homozygous for the hair length trait and could not afford genetic testing, which plan would be the best possible choice to give him this information?

1. Breed the animal with one that is homozygous for long hairless and watch for long hair offspring.
2. Breed the animal with one that is heterozygous for short hair and watch for long hair offspring.
3. Breed the animal with one that is heterozygous for short hair and watch for short hair offspring.
