Below are some examples of Drosophila mutants. Match each mutant with its description. apterous Bar Curly sepia vestigial Wrinkled yellow Antennapedia curled-up wings very small wings yellow body color wrinkled wings that fold against the body legs in place of antennae small eyes shaped like a bar no wings dark eyes Which of the above mutations are dominant to wild type? Which of the above mutations are recessive to wild type? Give the genotype of an apterous (ap) mutant. Give the genotype of a wild type that carries the apterous mutation. Give the genotype of a female white Give the genotype of a male white. Give the genotype of a female wild type that carries the white mutation.

Explanation / Answer

Apterous - No wing
Bar - Small eye shaped like a bar
Curly - curled up wings
Sepia - dark eyes
Vestigial -very small wing
Wrinkled - Wrinkled wing that folded against the body
Yellow - Yellow body color
Antennapedia - Legs in place of antennae

1. Dominant = Bar, Curly, Wrinkle, Antennapedia
2. Recessive = Apterous , Sepia, Vestigial, Yellow
3. Genotype Apterous = ap/ ap
4. Genotype of wild type carries Apterous mutation = Ap / ap
5. female while Xw Xw
6. Male white Xw Y
7. Female XR Xw
