1. The recessive Drosophila mutation bobbed (b) is located on the X chromosome and causes short bristles. The recessive, autosomal mutation ebony (e) causes a dark body color. Male flies homozygous for bobbed bristles and ebony body were crossed with homozygous wild-type females. The F1 are intercrossed to produce the F2. Answer the following questions using the gene notation listed above. A. List the genotypes of the parental flies: Male Females B. List the genotypes of the F1 flies: F1 male F1 females C. List the expected genotypes and sexes of the F2 flies and their phenotypic proportions.
