Hardy-Weinberg Equilibrium Part 2

What is the Hardy-Weinberg principle used for in population genetics?

• To predict how gene frequencies will change over time due to natural selection.

• To describe how populations evolve.

• To provide a mathematical model for studying evolutionary changes.

• To calculate the genetic variation of a population at equilibrium.

Which of the following conditions is NOT required for a population to be in Hardy-Weinberg equilibrium?

• Large population size

• Random mating

• No migration

• Differential survival of offspring

In the context of natural selection, what does "fitness" refer to?

• The physical fitness of an organism.

• The genetic superiority of an organism.

• The ability of an organism to survive and reproduce in its environment.

• The speed at which an organism can move.

What is an adaptation?

• A temporary change in an organism's behavior.

• A genetic trait that improves an organism's fitness.

• A non-genetic advantage in a specific environment.

• A mutation that has no effect on an organism's fitness.

How does natural selection affect allele frequencies in a population?

• It does not affect allele frequencies.

• It increases the frequency of beneficial alleles.

• It decreases the frequency of all alleles equally.

• It randomly alters allele frequencies.
