In consideration of the experiments of Thomas Hunt Morgan and eye color in Droso

Question

In consideration of the experiments of Thomas Hunt Morgan and eye color in Drosophilia, indicate the correct genotype of the parents of a cross between a white-eyed female fly and a red-eyed male fly under the indicated situation. If eye color is not sex-linked, what is the genotype of a while-eyed female parent? If eye color is not sex-linked, what is the genotype of a homozygous red-eyed male parent? If eye color is sex-linked, what is the genotype of a white-eyed female parent? If eye color is sex-linked, what is the genotype of a rod-eyed male parent?

Explanation / Answer

Answer: w+ is the wild type (dominant) allele and gives red colored phenotype. w is the recessive allele.

1. If eye color is not sex-linked, the genotype of a white eyed female parent = ww

2. If eye color is not sex-linked, the genotype of a homozygous red eyed male parent = w+w+

3. If eye color is sex-linked, the genotype of the white eyed female parent will be = ww

4. If eye color is sex-linked, the genotype of the red eyed male parent will be = w+Y
