In a group of fruit flies, the gene that determines the wing shape phenotype has two alleles. The allele for straight wings (W) is dominant to the allele for curly wings (w). In the same group of fruit flies, the gene for body color also has two alleles. The allele for brown body color (B) is dominant to the allele for black body color (b).
Two fruit flies that are heterozygous for both the wing and body color traits are crossed with each other.
Which phenotype is likely to be most common in the offspring of this cross?
