G In fruit flies, the genes black body (b), dumpy wings (dp), and hook bristles (hk) are all on the same chromosome. The dumpy gene is in the middle of the other two and is 18 cM away from the black gene and 24 cM away from the hook gene. The black and dumpy genes show the typical dominant and recessive relationship, with the mutant allele being responsible for the recessive phenotypes and the wild type alleles being responsible for grey bodies (b ) and long wings (dp ). The hook gene is different because it exhibits incomplete dominance, with Hk / Hk individuals having straight bristles and Hk / hk - heterozygotes having bristles with a slight curl, and homozygous recessive individuals with bristles that are hooked. You have access to a female fly that is heterozygous for all three of these genes. She has the black and dumpy wings coupled together but they are both in repulsion to the hook gene. Write out the genotype of this female, showing the linkage arrangement. Use and - to indicate wild type and mutant alleles and / to separate the chromosomes. Do not include spaces. What is the phenotype of this heterozygous female
