Which of the following statements applies to gain-of-function mutations? Gain-of-function mutations cause a protein to be active in extreme conditions such as high temperature. Gain-of-function mutations will only show a phenotype when heterozygous. Gain-of-function mutations are usually associated with dominant phenotypes. Gain-of-function mutations will only show a phenotype when homozygous.

Step 1: Gain-of-function mutations are usually dominant because the presence of the altered protein product is sufficient to produce a new phenotype. Show more…

When making the assumption of complete dominance, choose all the statements that are true about wildtype, mutant, recessive and dominant alleles: (choose all that apply) Group of answer choices -Dominant mutation alleles are always the result of gain of function mutations. -Recessive alleles usually cause an increase in functional protein expression. -If a person is heterozygous for a recessive disease allele, they normally possess 50% of the normal amount of protein. -A single copy of an allele showing complete dominance typically masks the effects of a recessive allele. -The most prevalent alleles in a population are called wild type alleles.
