Inbreeding is carried out in animal husbandry because it

1. increases vigour

2. improves the breed

3. increases heterozygosity

4. increases homozygosity

inbreeding increases homozygosity, i¢., state of possessing two identical alleles, one

inherited from each parent. itis necessary if we want to evolve a pureline in any animal

Inbreeding exposes harmful recessive genes that are eliminated by selection, It also

helps in accumulation of superior genes and elimination of less desirable genes.
