QUESTION
Full sibs and half-sib mating in poultry and parent- offspring or uncle- cousin mating in swine is most commonly used in?
OPTIONS
(A) Outcrossing
(B) Inbreeding
(C) Pure breeding
(D) Strain crossing
ANSWER
(B) Inbreeding
EXPLANATION
Inbreeding involves mating individuals that are more closely related than the average relationship in the population. Full-sib and half-sib matings in poultry and parent-offspring or related matings in swine are classic methods used to establish or maintain inbred lines. Outcrossing and crossbreeding instead introduce less-related or different-breed genetic material, while pure breeding is a broader breeding objective rather than the specific mating system described.
