Which of the following statements is true of the Hardy-Weinberg equation (p² + 2pq + q² =1)?

The "p" represents the frequency of the recessive allele for a specific trait in a population.

In order to use the equation, you have to know all of the genotype frequencies first.

The equation allows you to discover the genotype frequencies if you know the phenotype frequencies.

The Hardy-Weinberg equilibrium equation (p²+ 2pq + q² = 1) allows geneticists to:

keep track of changes in phenotype frequencies from generation to generation in small families.

keep track of changes in genotype frequencies from generation to generation in a population.

determine what evolutionary mechanisms are causing changes in a population's gene pool frequencies.

"Synthetic theory of evolution" refers to:

Which of the following statements is true?

In the real world, gene pool frequencies are inherently unstable. That is to say, they change by themselves without any evolutionary mechanism operating.

Evolution is a common occurrence in natural populations.

A gene pool is a more or less distinct group of individuals within a species who tend to restrict their mate selection to members of their group.
