Evolution

3. Which characteristic could not be used to determine the difference between two cryptic species of Hyla treefrogs
5. The classification of organisms based on their appearance is an application of which species concept.
7. Mechanism that explains how selectively neutral variants accumulate over time
8. Speciation resulting from the division of a population by a physical barrier is known as
9. Type of selection that favors average individuals leading to a reduction of variation in populations
11. Natural selection never directly favors the evolution of which type of reproductive isolating barrier

1. heterozygote genotype has a higher relative fitness than either the homozygous dominant or homozygous recessive genotype
2. Which species concept holds that “species are groups of actually or potentially interbreeding natural populations that are reproductively isolated from other such groups"
4. Type of selection that results in increased variation in the population
6. Type of selection when individuals at one extreme of a character distribution have higher fitness
10. Two species of monkeyflowers have diverged in the structure of their flowers such that they can no longer be effectively pollinated by the same pollinator species. This is an example of which type of isolation
