Question

If an allele is recessive and lethal in homozygotes before they reproduce,
a. the allele will be removed from the population by natural selection in approximately 1,000 years.
b. the allele will likely remain in the population at a low frequency because it cannot be selected against in heterozygotes.
c. the fitness of the homozygous recessive genotype is 0.
d. both b and c are correct.

Accepted Answer

Hello everyone here We have a question asking us which of the following increases the frequency of the deleterious alleles in a population inbreeding can cause loss of hetero Z. Gossipy with no expected change in a little frequency. So even though we're becoming more we're having more homo zygotes, the little frequencies aren't changing. Whenever deleterious alleles are at least partially recessive. Inbreeding exposes these old wheels and homo zygotes. And this can decrease the main fitness of individuals within the population, whereas continuous gene flow and actual selection actually increased species fitness. So our answer here is c inbreeding. Thank you for watching. Bye.
