Question

Quizplus · Accepted Answer

A conditional loss-of-function mutation only affects the phenotype under specific conditions or in specific contexts, such as temperature or developmental stage. Hypomorphic mutations result in a partial loss of function but are not dependent on special circumstances. Null mutations result in a complete loss of function, while dominant-negative mutations affect both wild-type and mutant alleles.
