If both assertion and reason are true and reason is the correct explanation of assertion

Inbreeding refers to the mating of closely related individuals within the same breed for 4 - 6 generations. Superior males and superior females of the same breed are identified and mated in pairs. The progeny obtained from such matings are evaluated and superior males and females among them are identified for further mating. Inbreeding increases homozygosity. Thus inbreeding is necessary if we want to evolve a pureline in any animal.
