Answer: see explanation
Explanation:
The response includes the explanation that the presence of Notonecta chemical cues enhanced expression of genes associated with crest development in the Daphnia.
Notonecta is insects, which are found in the marine environment. The chemical cues used by insects are to communicate, locomotion, and protection.
Notonecta uses chemical cues, which may affect the gene expression in Daphnia.
The Daphnia are the small planktonic crustaceans, which are commonly known as water fleas. The Notonecta chemical cues affect the gene expression in Daphnia by changing the phenotype.
The changes were occurred only in the developmental stages of Daphnia but were not inheritable. The offspring are not expected to have larger crest sizes and widths in a predator-free environment.
Therefore, the gene expression of Daphnia was affected by the chemical cues released by Notonecta.
