Answer 1

The generation of reproductive isolating mechanisms—geographic, behavioral, physiological, and mechanical—provides common factors in the speciation process.

Answer 2

Fitness is a measure of the proportion of offspring that a particular phenotype will contribute to the next generation; the selection coefficient is the mathematical difference between the actual fitness of a given genotype and the optimal fitness for an individual in a given population.
