Vedclass · Answer

(A) Inbreeding refers to the mating of more closely related individuals within the same breed for $4-6$ generations.Continued inbreeding,especially close inbreeding,usually reduces fertility and even productivity. This phenomenon is known as inbreeding depression.Inbreeding increases homozygosity. This exposes harmful recessive genes that are eliminated by selection,but if continued,it leads to the accumulation of these deleterious recessive alleles,which negatively affects the fitness and fertility of the offspring.Therefore,both the assertion and the reason are correct,and the reason provides the correct explanation for the assertion.

Assertion $A$: Continued inbreeding is not desirable.
Reason $R$: The fertility of offspring decreases due to the accumulation of harmful recessive genes.
