The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Inbreeding refers to the mating of closely related individuals within the same breed for 46 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.
