Which statement regarding genetic diversity is most accurate?
A)Larger genes are more likely to display diversity than small genes.
B)Genetic diversity is significant only when a population is isolated.
C)Genetic disorders are more common in populations that have greater genetic diversity.
D)Population bottlenecks result in loss of alleles that provide minimal selection advantage.

Question

Quizplus · Accepted Answer

Genetic diversity in the form of single-nucleotide polymorphisms is much more common in alleles of larger genes than those of smaller genes (one sequence variation for every 200 to 500 nucleotides). Lack of genetic diversity occurs in isolated populations. Genetic disorders are more common in populations with less genetic diversity. When diversity is greater, there are more alleles for genes, reducing the likelihood of inheriting two alleles that cause disease or disorders. When population bottlenecks occur, alleles are lost randomly, without regard to whether the allele confers a selection advantage or not.
