B)ll BB
C)ll Bb
D)ll bb

Quizplus · Accepted Answer

To determine the genotype of a black short-haired animal (which shows dominant traits), you would cross it with an animal that has homozygous recessive traits for both characteristics (long brown hair, or ll bb). This would reveal whether the black short-haired animal carries recessive alleles, based on the phenotypes of the offspring.
