Question
Inbreeding.
✓
Answer
Inbreeding is the mating of two closely related individuals of the same breed for 4 to 6 generations.
During inbreeding superior males and superior females of the same breed are identified. The superior males and superior females from this progeny are identified and used for further mating.
Due to inbreeding, homozygosity is increased and harmful recessive genes are exposed. Inbreeding is done when a pure line of an animal is expected.
Inbreeding helps in accumulation of superior genes and elimination of harmful or less desirable genes.
Continued inbreeding usually reduces fertility and productivity. This is called inbreeding depression.
