Drosophila, the allele red eyes (bw+) is dominant to the allele for brown eyes (bw). at another gene locus on the same chromosome, the allele for thin wing veins (hv+) is dominant to the allele for heavy wing veins (hv). flies homozygous for bw and hv+ are crossed to flies homozygous for bw+ and hv to obtain doubly heterozygous f 1 progeny. what would be the results of a test cross with the f 1 flies?

a. 1 brown eye, heavy wing veins:

b. 1 red eye, thin wing veins 1 brown eye, thin wing veins:

c. 2 red eye, thin wing veins:

d. 1 red eye, heavy wing veins 1 brown eye, heavy wing veins:

e. 1 red eye, heavy wing veins.
