When can a new, heritable phenotype become advantageous?
When an environmental change makes it better suited to the conditions.
How can an advantageous heritable phenotype affect an individual’s survival and reproduction?
The individual may be more likely to survive and reproduce, passing the associated genetic variant to offspring.
How can selection affect the frequency of an advantageous phenotype and its associated genetic variant over generations?
Both can become more common in the population.
How quickly can selection of an advantageous new phenotype change a species?
It can cause a relatively rapid change.
