Which situation is an example of competition that could be found in the ocean?
Naddika [18.5K]

Answer:

3

Explanation:

Heterozygous mice at both loci would be BbAa genotype.

B (black) is dominant over b (white) but the presence of A results in agouti.

Crossing two heterozygous:

     BbAa    x    BbAa

Progeny

<em>9 B_A_ - Agouti</em>

<em>3 bbA_ - agouti</em>
