Question

question 6 1 pts when a brightly colored guppy population is placed in an area containing many predators, the population changes in only a few generations to one containing only guppies with drab, dull colors that blend into their environment. this is an example of how natural selection can
○ force new color mutations to occur.
○ convert a dominant allele into a recessive allele.
○ improve the match between guppies and their environment.
○ change the color preferences of female guppies.

Explanation:

1. Analyze Option 1: Natural selection acts on existing variations, not force new mutations. Mutations are random, so this is incorrect.
2. Analyze Option 2: Natural selection doesn't convert allele dominance; dominance is a genetic trait, so this is wrong.
3. Analyze Option 3: The guppies' color change to dull (blending with environment) helps survival (avoid predators), so natural selection improves their match with the environment. This fits.
4. Analyze Option 4: The scenario is about predator - prey and survival, not female guppies' color preferences, so this is incorrect.

Answer:

C. improve the match between guppies and their environment
