Question

A breed of cow is mated with closely related breed for five generations. It was found that production of milk has reduced subsequently and the animals are not keeping good health. Which of the following methods of animals breeding can overcome this problem?

Answer 1

Answer:

Continued inbreeding reduces fertility and productivity. This is called inbreeding depression. This problem can be overcome by out-crossing. Out-crossing is the practice of mating of animals within the same of their pedigree upto 4−6 generations. The offspring of such a malting is known as out-cross. A single outcross often helps to overcome inbreeding depression.
