1. In goldfish, golden scales is a dominant trait. Use G to represent the dominant trait and g to represent the recessive trait
of white scales. Predict the outcome of a cross between a heterozygous golden scale fish and a white scaled fish. What phenotype ratios will the offspring have? 2. In ostriches, incomplete dominance is shown in beak color. The beak colors are red, yellow, and orange. Orange is a phenotype of the red and yellow allele combination. What is the expected phenotypic outcome of mating a yellow and orange beaked bird?
3.One pair of genes for coat color in cats is sex-linked and shows incomplete dominance. Gene Y produces yellow coats and is located in the X chromosome (XY ). Gene B produces a black coat (XB). Heterozygous (XB XY) produces a tortoise shell coat.
Why will there never be any tortoise shell males and What kind of offspring will result from mating a yellow male and a black female?
