In drosophila, the recessive trait black body is controlled by
the b allele. The b+ allele results in the normal gray body color.
The recessive trait “dumpty” short wings is controlled by the dp
allele. The dp+ allele encodes for the normal long wings. The
recessive trait hooked bristles is controlled by the hk allele. The
hk+ allele results in normal bristles. A phenotypically wild- type
fly heterozygous for alleles of all three genes is crossed with a
dumpy, black, hooked male. Progeny with the pheno- types given
below result from this cross. (Assume that traits not mentioned in
a particular phenotypic class are wild-type.)

Progeny with the phenotypes given below result from this cross. (Assume that traits not mentioned in a particular phenotypic class are wild-type.) What was the genotype of the female parent? Do not worry about the order of genes on the chromosomes. What is the correct gene order for the three genes? What is the map distance in cM between dp and b?
