If a certain recessive allele can cause a change in cellular proteins that ultimately leads to circulatory problems and premature death, then
A) any homozygous individual will always have an advantage over any heterozygous individual.
B) any heterozygous individual will always have an advantage over any homozygous individual.
C) any homozygous individual will always have a disadvantage compared to any heterozygous individual.
D) any heterozygous individual will have an advantage over any homozygous recessive individual.

Quizplus · Accepted Answer

individuals who are heterozygous for the allele will have at least one copy of the normal version of the protein, which may be enough to prevent or delay the onset of the circulatory problems associated with the recessive allele. Homozygous individuals for the recessive allele will only produce the abnormal protein, leading to greater risk for circulatory problems and premature death. Therefore, heterozygous individuals will have an advantage over homozygous recessive individuals.
