Q: The relative concentrations of brown and red eye pigment in Drosophila can be qu

Answer: Hypomorphic mutation: A mutation, which results in partial loss of expression but less than wild type. Hypermorphic mutation: Any mutation, which leads to the over-expression or over-activity (relative to wild type) of the relevant protein. Amorphic mutation: this type of mutation leads to the complete loss of expression. QA Answer: B QB Answer: C QA Answer: A

Question

The relative concentrations of brown and red eye pigment in Drosophila can be quantified by the absorption of different wavelengths of light in an extract. Three different mutations affecting brown pigment protein concentrations were tested as homozygotes, heterozygotes with wildtype, and as hemizygotes over a deletion. The results (concentrations relative to wildtype homozygotes) are given below. Which mutant would be considered a hypomorph? A B C Which mutant would be considered a hypermorph? A B C Which mutant would be considered an amorph? A B C

Explanation / Answer

Answer:

Hypomorphic mutation: A mutation, which results in partial loss of expression but less than wild type.

Hypermorphic mutation: Any mutation, which leads to the over-expression or over-activity (relative to wild type) of the relevant protein.

Amorphic mutation: this type of mutation leads to the complete loss of expression.
