You are given the task of creating a genetic map of three genesof Drosophila melanogaster . The genes are all located on the samechromosome. The genes are for body color, eye color and antennaformation. The alleles for body color are yellow and gray(wild-type), the alleles for eye color are sepia and red(wild-type) and the alleles for antenna are short and normal(wild-type). The mutant alleles for body and eye color arerecessive, while the mutant allele for antenna formation isdominant. You follow the procedure for determining the order andmap distance for the genes and obtain the following data: Short,gray, sepia = 240 Short, yellow, red = 2 Short, yellow, sepia = 500Short, gray, red = 22 Normal, yellow, red = 270 Normal, gray, sepia= 5 Normal, yellow, sepia = 15 Normal, gray, red = 444 Hints fordrawings: size matters! Don’t draw all genes equidistant. If twogenes are further away from each other than another set, make sureto draw it that way. Based on the data given:

a) Define each gene and allele. Based on how you defined thealleles, what was the genotype and phenotype of the P gen? Makesure to notate alleles properly and to draw the chromosomescorrectly. Make sure the genes are in the correct order.

b) What was the genotype and phenotype of the F1 gen? Make sureto notate alleles properly and to draw the chromosomes correctly.Make sure the genes are in the correct order.

c) What was the genotype and phenotype of the Test cross thatwas performed? Make sure to notate alleles properly and to draw thechromosomes correctly. Make sure the genes are in the correctorder.

d) What are all of the map distances between the genes given?Make sure to draw the chromosomes correctly, the genes are in theproper order and units are used.
