Question

Which breeding is used to overcome inbreeding depression?

• A. Out-crossing
• B. Cross-breeding
• C. Interspecific hybridisation
• D. Inbreeding

Answer 1

Answer:

A. Out-crossing

• 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.
