Inbreeding is carried out in animal husbandry because it:

• Inbreeding is defined as the mating of more closely related individual within the same breed for 4-5 generation.

• Individuals produced by inbreeding are exactly similar to their parents and hence are considered as purelines.

• Homozygosity is referred to as condition in which the animal has identical alleles in a pair.

• Inbreeding results in transfer of same alleles generation to generation, hence, causing homozygosity.

• Inbreeding results in the production of purelines, thus there is no chances of increased vigour.

• Same alleles throughout many generations also do not guarantee improved breed.

• Same alleles are passed in inbreeding so heterozygosity does not increase.

• Inbreeding produces pureline, hence increasing homozygosity.

Hence, Inbreeding is carried out in animal husbandry because it increases homozygosity.
