Suppose there is a vial containing a single generation of flies from a cross. there is an interesting phenotype where many individuals have abnormally long hairlike bristles, sensory organs extending from the dorsal thorax, as opposed to the short wirelike wild-type bristles among the other siblings. references state that this mutant has a dominant mutation called suave (su) and that the phenotype of flies that are heterozygous or homozygous for su appear phenotypically identical. which fly should be crossed to a suave male from this vial in order to generate progeny that determine the male\'s genotype
