Predict the ratios of phenotypes among the offspring

Reference no: EM1389802

Question: The genes for body color and wing size in Drosophila are on the same chromosome. The symbols for the alleles are: b+ = gray, b = black, vg+ = normal wings and vg = vestigial wings, with gray and normal wings as the dominant phenotypes. If a fly having alleles b+ and vg+ on one chromosome and b and vg on its homolog is mated with a black fly with vestigial wings, predict the ratios of the following phenotypes among the offspring, assuming that no crossing over occurs:
gray-normal : black-vestigial : black-normal : gray-vestigial
