Question

A single pair of goldfish in a aquarium produced a large number of offspring.

These offspring showed variations in body shape and coloration.

The most likely explanation for these variations is what?


(A.) Offspring were adapting to different environments.

(B.) Parent fish had not been exposed to mutagenic agents.

(C.) Offspring were produced from different combinations of genes.
​

Answer 1

C. Offspring were produced from different combinations of genes.

Step-by-step explanation:

The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.
