Artificial hybridization helps to develop quantitative outcomes in the cattle. Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. It results in homozygosity, which can increase the chances of offspring being affected by deleterious or recessive traits. An individual who inherits such deleterious traits is colloquially referred to as inbred.

Inbreeding refers to the breeding of more closely related individuals within the same breed for 4-6 generations. It results in an increase of homozygosity. Due to continuous inbreeding, it reduces fertility and even productivity. It is called inbreeding depression.
