Question

3. Consider the following scenario:
In a muddy lake environment, some fish have brown scales. Most fish, however have silver scales. Predators have a harder time seeing the fish with brown scales.
A. Predominant phenotype
B. Inactivated gene
C. New mutation
D. Advantageous trait

Answer 1

In the scenario you provided, where fish with brown scales are less visible to predators in a muddy lake environment compared to fish with silver scales, the correct answer would be:

**D. Advantageous trait**

This is because the brown scales provide a survival advantage in that specific environment, making those fish less likely to be seen and eaten by predators.
