1. A genetic condition, due to a recessive allele (a), is deadly in homozygous individuals

(aa), while heterozygous individuals (Aa) are not affected. Based on this information,

which of the following is likely to result?

a. The disorder will quickly be eliminated since no homozygous recessive individuals will survive

to reproduce

b. Only homozygous dominant (AA) individuals will survive.

C. The disorder will be maintained in the population through the reproduction of heterozygous

individuals.

d The prevalence of the disorder will increase quer time

Answer:C. The disorder will be maintained in the population through the reproduction of heterozygous individuals.

Explanation: Since the genetic condition is deadly in homozygous individuals, all individuals who are homozygous for the recessive allele will die, therefore only the individuals who are heterozygous for the recessive allele will survive because the allele is not deadly in a heterozygous condition. Therefore, the disorder will continue to stay in the population through the reproduction of individuals who are heterozygous for the recessive allele.
