Track Trait Frequency Practice Test

Because bright tails decrease after Generation 2, the trait is gone forever and cannot return.

The frequency of bright tails cannot change because the population size stays 30 each generation.

Bright tails become more common from Generation 1 to Generation 5, even though they do not increase every generation.

Bright tails are the most common in Generation 2, so the frequency must keep increasing after Generation 2.
