1-

The genotype D_E_ (where the _ indicates that either the dominant or recessive allele is present) results in a wild type phenotype. All other genotypes result in the same mutant phenotype. If the cross DdEe x DdEe is peformed, what is the expected phenotypic ratio?

2- The genotypes D_E_, D_ee and ddee all result in a wild type phenotype. ddE_ gives a mutant phenotype. If the cross DdEe x DdEe is peformed, what is the expected phenotypic ratio?

3- The genotypes D_E_ and D_ee result in a wild type phenotype. ddE_ gives one mutant phenotype and ddee gives a different mutant phenotype. If the cross DdEe x DdEe is peformed, what is the expected phenotypic ratio?

In Drosophila, the gene for white (w) eyes is on the X chromosome and it is epistatic over brown and scarlet. White eyes can also result by crossing brown-eyed females (bw) with scarlet eyed males (st) (that is, when both mutant alleles are present).A cross is made between white-eyed females with the genotype w//w (otherwise, homozygous for wild type alleles) and white-eyed males hemizygous for the wild type allele (w+ ). List the expected: a) Genotypes of the P1 and...
