Which breeding is used to overcome inbreeding depression?(a) Out-crossing(b) Cross-breeding(c) Interspecific hybridisation(d) InbreedingThe question was posed to me in a job interview.My doubt is from Animal Breeding in section Strategies for Enhancement in Food Production of Biology – Class 12

Answer»

Correct option is (a) Out-crossing

To explain I would SAY: CONTINUED inbreeding, especially close inbreeding, USUALLY REDUCES fertility and even productivity. This is called inbreeding depression. Whenever this becomes a problem, selected animals of the breeding population should be mated with unrelated animals of the same BREED. This is called as outcrossing and it often helps to overcome inbreeding depression.
