Question

Compare: Compare the rate at which the deleterious d allele disappears in this activity to the rate at which the deleterious D allele disappears in activity A.

A Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
B Why do you think this is so?

Answer 1

A. In this activity, the deleterious d allele disappears more rapidly compared to the deleterious D allele in activity A.

B. This is likely because the deleterious recessive allele (d) can be masked by the dominant allele (D) in heterozygous individuals. As a result, the deleterious d allele is less likely to be expressed in the population compared to the deleterious D allele. Therefore, the d allele is more easily eliminated from the population through natural selection.
