## How do you calculate Hardy Weinberg equilibrium?

Knowing p and q, it is a simple matter to plug these values into the Hardy-Weinberg equation (p² + 2pq + q² = 1). This then provides the predicted frequencies of all three genotypes for the selected trait within the population.

## Why is the Hardy-Weinberg equilibrium useful?

Importance: The Hardy-Weinberg model enables us to compare a population’s actual genetic structure over time with the genetic structure we would expect if the population were in Hardy-Weinberg equilibrium (i.e., not evolving).

## Is the Hardy-Weinberg model realistic?

Explanation: All of the answer choices are assumptions made when considering Hardy-Weinberg equilibrium. Thus, the model is not very realistic in nature, since these conditions are rarely met. Also, no natural selection is assumed to occur.

## Are the Generation 5 values for P and Q?

Are the Generation 5 values for p and q different from their initial values? No, they are the same. (Note: Because of the small size of the simulated population, there may be some variation in your class results.

## How do you calculate P and Q?

To find q, simply take the square root of 0.09 to get 0.3. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers).

## What happens if the Hardy-Weinberg equilibrium is violated?

Eggs and sperm collide at the same frequencies as the actual frequencies of p and q. When this assumption is violated and by chance some individuals contribute more alleles than others to the next generation, allele frequencies may change. This mechanism of allele change is called genetic drift.
