A mutant allele results in a truncated form of a signaling protein.This protein can still bind its receptor protein but does not activate the receptor and inhibits wild-type signaling proteins from binding the receptor.What type of allele is this mutant allele?
A)hypomorphic allele
B)hypermorphic allele
C)neomorphic allele
D)antimorphic allele

Quizplus · Accepted Answer

This mutant allele is an example of an antimorphic allele because it produces a protein that not only fails to perform its normal function (due to truncation) but also interferes with the function of the wild-type protein. This interference is a hallmark of antimorphic alleles, often referred to as dominant negative mutations.
