Question

Trocanian Sea Lions, on the planet Peskus, have whisker length determined by two unlinked loci, labeled A and B. A partial set of two-locus genotypes and their corresponding whisker lengths is presented in the table below. What is the whisker length of a Sea Lion with the two-locus genotype AABb?

A. 4.

B. 5.

C. 1.

D. 2.

E. 3.

Trocanian Sea Lion Whisker Length As Computed By Two-Locus Genotype Locus 01 Genotype Locus 02 Genotype Whisker Length A A b b 2 A a B B 4 A a B b 2 A a b b 1 a a B B 2 a a B b 1 A A B B 5

Explanation / Answer

Answer:
