In tribbles, amiable (A) is dominant to mean (a), blue (B) is dominant to white (b), and dorky (D) is dominant to cool (d). A pure-breeding amiable, white, dorky tribble was mated to a mean, blue, cool tribble. The FI was then test-crossed and produced 4000 offspring (those tribbles). Star Fleet records indicate that all three traits are autosomal, A and B are linked and they are 20 mu. from each other, while D is not linked to either.

A. Predict the expected phenotypes, genotypes (you can neglect the test cross contribution notation) and numbers of the F2 offspring

GENOTYPES PHENOTYPES NUMBER

B. Indicate with arrows the classes above that would not be produced if A and B were completely linked.
