In fruit flies, long wings (L) are dominant over short wings (II), and gray body (G) is dominant over black body (gg). If a heterozygous long wing, black-body fly (Llgg) reproduces with a short wing, heterozygous gray-body fly (IIGg), what phenotypic ratio is expected among the offspring?

In garden peas, yellow seed is dominant over green. If a homozygous yellow-seeded plant is crossed with a green seeded plant, what will be the phenotypic ratio in the second generation after this cross?

Assume that an incompletely dominant gene controls the feather color in chickens so that BB produces black, BW produces a slate-gray color called blue, and WW produces asplashed-white. A second gene on a separate chromosome controls comb shape, with the dominant gene R producing a rose comb and the recessive genes rr producing a single comb. A homozygous black, single comb-chicken is mated with a homozygous white, rose-comb chicken. The offspring are the allowed to breed freely among themselves. What proportion of their offspring (this would be the second filial (F2) generation) would have white feathers and single comb?

In fruit flies, red eye color is dominant over white and eye color is sex linked on the X chromosome. A white-eyed male is mated with a homozygous red-eyed fema1e. What percent of the offspring will be red-eyed males?
