In Drosophila, the gene eyeless (ey) is on the fourth chromosome, and four wings (fw) and legs for antennae (lfa) are both on the third chromosome 20 cM apart. Consider that mutations in all three genes each cause recessive phenotypes. What frequencies would you expect for the various phenotypes amongst the offspring of the test cross shown below (note that the comma separates alleles on the same chromosome, and the semicolon separates different chromosomes):

In Drosophila, the gene eyeless (ey) is on the fourth chromosome, and four wings (fw) and
legs for antennae (lfa) are both on the third chromosome 20 cM apart. Consider that mutations
in all three genes each cause recessive
various phenotypes amongst the offspring of the test cross shown below (note that the comma
separates alleles on the same chromosome, and the semicolon separates different
