This Figure Shows the Tail Shape Developed by Three Tadpole

question 64

Multiple Choice

This figure shows the tail shape developed by three tadpole genotypes (M, N, and O) when raised in an environment with predators and an environment without predators. In the presence of predators, tadpoles with large tails have high fitness and tadpoles with small tails have low fitness. When predators are not present, tadpoles with large tails have low fitness and tadpoles with small tails have high fitness. Under which of the following situations would the plastic genotype be favored over other genotypes?
I. if all environments have predators
II. if no environments have predators
III. if environments with predators are as common as environments without predators

• A) situation I
• B) situation II
• C) situation III
• D) situations I and II
• E) situations I and III
