What is a mating in which an individual showing the dominant phenotype is crossed with an individual expressing the recessive phenotype?

Brown eyes are dominant over blue eyes. This is NOT a sex linked trait. Cross a brown eyed Color blind male (whose mother had blue eyes) with a normal blue eyed female (whose father was colorblind)

In fruit flies, the wild type (red) eye colour is dominant to white eye colour. This gene is carried on the X chromosome. The allele for wild type body colour is dominant to ebony body colour. This gene is carried on the autosome. A wild type female fruit fly that is homozygous for both traits mates with a male fruit fly with white eyes and ebony body colour. What phenotypic ratio would be expected in their offspring? Ratio: A female with red A female with white A male with red A male with white Phenotype: eyes and wild type eyes and ebony eyes and wild type eyes and ebony body colour body colour body colour body colour
