How can the hardy-weinberg equation be used to model selection?

Answer 1

The Hardy-Weinberg principle is used when describing a population of organisms in which the organisms do not change.

This principle explains the requirements of a population in order to remain constant (no mutations or evolution) for generations. So basically, there would be no natural selection. All the organisms would be equally adapted to their environment and distribute genes throughout a population.

The Hardy-Weinberg principle includes factors such as movement in and out of a population, mate choice, mutation, selection, genetic drift, and meiotic flow when describing a population which does not change. All of these previous factors must remain constant i.e. no movement in and out of a population, because this would bring new genes into the pool.

The Hardy-Weinberg equation can be used to model selection by comparing the allele frequencies in a population under idealized conditions (no mutation, migration, genetic drift, or natural selection) with those observed in the actual population. Any deviation from the expected frequencies can indicate the presence and magnitude of selection pressures acting on the population.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
