In Drosophila, an allele causing vestigial wings is 12.5 mu awayfrom another allele that causes purple eyes. A third gene that affectsbody color has an allele that causes black body color. Thisthird gene is 18.5 mu away from the vestigial wings allele and 6mu away from the allele causing purple eyes. The alleles causingvestigial wings, purple eyes, and black body are all recessive.The dominant (wild-type) traits are long wings, red eyes, and graybody. A researcher crossed wild-type flies to flies with vestigialwings, purple eyes, and black bodies. All F1 flies were wild type.F1 female flies were then crossed to male flies with vestigial wings,purple eyes, and black bodies. If 1000 offspring were observed,what are the expected numbers of the following types of flies? long wings, red eyes, gray bodylong wings, purple eyes, gray bodylong wings, red eyes, black bodylong wings, purple eyes, black bodyshort wings, red eyes, gray bodyshort wings, purple eyes, gray bodyshort wings, red eyes, black bodyshort wings, purple eyes, black body
