The amount of enzyme activity in a cell that is homozygous for a mutant allele is 400 units. The amount of enzyme activity in a cell homozygous for the wt allele is 200 units. The amount of enzyme activity in a heterozygote is 300 units. What type of allele is the mutant allele?
Hypomorphic Alleles
: A change that reduces, however, doesn't dispense with a gene's usefulness is hypomorphic. A progressively extreme condition, amorphic transformation, dispenses with the gene's capacity.
The great analyses characterizing hypomorphic alleles go back to the 1930s. Herman Miller, who won a Nobel Prize for finding that radioactivity causes changes, considered the eyeshade of organic product flies. These flies typically have red eyes, yet freak assortments can have white or apricot-hued eyes. The allele liable for various natural product fly-eye hues is known as the white allele, with the contraction "w."
