Question

Consider a recessive mutation that results in a complete loss of gene function. If heterozygous individuals (mutant/wild-type) are phenotypically wild-type, then the wild-type allele would be described as being __________. See Section 4.1 (Page 107) .

Answer 1

Answer:

dominant

Explanation:

In this example, if heterozygous individuals that carry one wild type allele and one mutant allele (mutant/wild-type) are phenotypically wild-type, then, the wild-type allele is dominant. This is explained by the fact that wild-type is expressed, even when mutant allele produces a non-functional gene.
