The phenotype of vestigial (short) wings (vg) in drosophila melanogaster is caused by a recessive mutant gene that independently assorts with a recessive gene for hairy (h) body. assume that a cross is made between a fly with normal wings and a hairy body and a fly with vestigial wings and normal body hair. the wild-type f1 flies were crossed among each other to produce 1024 offspring. which phenotypes would you expect among the 1024 offspring, and how many of each phenotype would you expect?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4

3. in the fruit fly, recessive mutation brown, b, causes brown color of the eye and absence of red pigment. recessive mutation p of another independent gene causes purple color of the eye and absence of brown pigment. the cross of a brown-eyed female and purple-eyed male produced wild type eyes. what will be the colors and their ratio in f2?
