The genes for body color and wing size in Drosophila are on the same chromosome. The symbols for the alleles are:

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:
