e-lub [12.9K]

Answer:

There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).

Explanation:

This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.

However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.

Allisa [31]

Answer:

AaBb, AABb, AaBB, AABB, Aabb, aaBb, AAbb, aaBB, aabb.

Explanation:

Gene A conditions pigment type.

Gene B determines whether the pigment of A will be deposited.

Heterozygous black individuals will have the genotype AaBb.

Two heterozygous black individuals were crossed:

AaBb x AaBb

Progeny:

4 AaBb - Black

2 AABb - Black

2 AaBB - Black

1 AABB - Black

2 Aabb - yellow

2 aaBb - yellow

1 AAbb - brown

1 aaBB - brown

1 aabb - brown

<em>Hence, the genotypes of the offspring are:</em>

AaBb, AABb, AaBB, AABB, Aabb, aaBb, AAbb, aaBB, aabb.

See the attached image for the Punnet's square result of the cross.
