Use the following to answer questions :
Dr. Disney has been raising exotic fruit flies for decades. Recently, he discovered a strain of fruit flies that in the recessive condition have baby blue eyes that he designates as bb. He also has another strain of fruit flies that in the recessive condition have pink wings that are designated as pw. He is able to establish flies that are homozygous for both mutant traits. He mates these two strains with each other. Dr. Disney then takes phenotypically wild-type females from this cross and mates them with double recessive males. In the resulting testcross progeny, he observes 500 flies that are of the following makeup:
41with baby blue eyes and pink wings
207with baby blue eyes only
210with pink wings only
42with wild-type phenotype
-What is the relationship with respect to location between the two genes?

A) They are far apart on the same chromosome and assorting independently.
B) They are linked and the map distance between them is 41.5 m.u.
C) They are on different chromosomes and assorting independently.
D) They are linked and 16.6 m.u. apart.
E) They are linked and 50.0 m.u. apart.
