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.
