Answer:
The relative size of the crest height and width of offspring raised in the tank without chemical cues is lower as compared to the parent Daphnia.
Explanation:
The size of the crest of Daphnia is directly related to the chemical cues secreted by the Notonecta. If the water has Notonecta , the size of the crest of Daphnia is increases because the crest is sensitive with the release of the chemical cues of Notonecta. So if the water has no chemical cues, the size of the crest height and width of offspring is lower as compared to the parent Daphnia.
