Passage II
Each dog in a particular population has a black brown, or yellow coat. In this population, coat color is determined by 2 unlinked genes: Gene B and Gene E. Gene B has 2 alleles: B and b. Gene E also has 2 alleles: E and e. Table 1 shows the possible genotypes for Gene B and Gene E and the resulting coat color phenotypes.
Two of the dogs with black coats were crossed 3 times (Crosses 1-3). The coat colors of the offspring produced in each cross are shown in Table 2.
9. What was the Gene B and Gene E genotype of the off-spring of Cross 2 that had a brown coat?
Your Answer is
Correct Answer is D
Explanation
From table 1, it can be seen that the genotype corresponding to brown coat is bbEE or bbEe, so D should be selected
