In Drosophila, the allele red eyes (b) 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 F1 progeny. What would be the results of a test cross with the F1 flies?
