Drosophila melanogaster females heterozygous for three linked autosomal genes (a,b, and c) are testcrossed with triple homozygous recessive males. The map distances are a-b 10 map units, b-c 20 map units, a-c 30 map unit, and the genes are in coupling, that is: all the recessive genes are on the same chromosome. Answer the following questions:

a. What percentage of the testcross progeny are genotype ab/ab?

b. What percentage of the testcross progeny are genotype Ac/ac?

c. What percentage of the testcross progeny are genotype bC/bc?
