Dominant negative
Explanation:
Dominant negative represents a class of mutation in which a mutant receptor interferes with the function of the wild-type version of the receptor.
null/amorphic: It is a form of mutation that causes the complete loss of Gene function (protein) by disrupting translation and/or preventing transcription.
Neomorphic: Describes a mutation where altered gene product possesses a completely new molecular function and sometimes pattern of gene expression.
Hypmorphic: describes a mutation that causes a partial loss of gene function usually through reduced (protein, RNA) expression or reduced functional performance.
hypermorphic: describes a mutation that causes an increase in the normal gene function resulting from increased mRNA or protein expression.
