Question

You've been studying the spotted homework bug - a pesky little creature that appears to be a tailed relative of Xenophyes rhachilophus, the moss bug. You've discovered two new mutants, and you've been characterizing them genetically. The phenotype of the wild-type spotted homework bug is shown below. With reference to the genotype, the mutant allele is designate "mutant," the wild-type allele is designated "+"and a deletion of the gene is designated "Df." The forward slash (f) separates alleles. Based on these results, how would you characterize the spotted homework bug mutant 1 allele? For parts A & B, assume that mutants 1 and 2 identify independent genes. ANSWER:

Explanation / Answer

Amorphic is not the answer, as the second and third one is not normal. If the coded protein would be a dimer then the second one at least should have been normal.

hyporphic (same applies here too)

Antimorphic is not the answer, as the severity of the second one would have been less that the third one, due to double copy of wild type gene compensation.

Neomorphic is not the answer, as the second and the third would have been of the same phenotype.

Answer is hypermorph, as the increase in the wild type dosase has worsened the phenotype in the second.
