Question: Regarding assertion and reason, choose the correct option. Assertion [A]: Excessive inbreeding leads to inbreeding depression Reason [R]: Increased homozygosity leads to loss of heterozygosity WebInbreeding increases the chance that a gene obtained from the sire will match one obtained from the dam, both stemming from the common ancestor(s) on which the individual was inbred. Thus, inbreeding tends to make animals homozygous rather than heterozygous. The inbreeding coefficient measures the resulting increase in homozygosity.

WebMar 15, 2016 · Decreasing fitness with increasing inbreeding is a widespread phenomenon (), which occurs because mating between relatives increases homozygosity at loci carrying rare recessive deleterious alleles or exhibiting overdominance ().The magnitude of inbreeding depression is relevant to many disciplines within biology, including the … Webif you are asking whether inbreeding increases homozygosity, the answer is yes because that is how we breed domestic animals to have the genetic characteristics we want. The problem is that inbreeding also increase the likelihood that there is homozygosity of deleterious alleles; those that cause disease or may result in death.

WebMay 6, 2024 · (1) Inbreeding increases homozygosity (2) Inbreeding is essential to evolve purelines in any animal. (3) Inbreeding selects harmful recessive genes that reduce … WebInbreeding reduces survival and reproduction (i.e. it causes inbreeding depression), and thereby increases extinction risk. Inbreeding depression is due to increased homozygosity for harmful alleles and at loci exhibiting heterozygote advantage.

WebApart from ethical considerations, a negative outcome of inbreeding is that it increases the likelihood of homozygosity of deleterious recessive alleles originating from common ancestors, ...
