What does the HW equation predict for P and Q?

What does the HW equation predict for P and Q?

An equation called the Hardy Weinberg equation for the allele frequencies of a population is p2+ 2pq+ q2 = 1. P represents the A allele frequency. The letter q represents the a allele. Hardy and Weinberg also gave five conditions that would ensure the allele frequencies of a population would remain constant.

What would you expect to happen to the frequencies of p and q If you ran the simulation for another five generations?

Predict what would happen to the frequencies of p and q if you simulated another five generations. The p value would continue to increase, and the q value would decrease.

How do you solve Hardy-Weinberg Problems?

1. Step 1: Assign the Alleles. • By convention, we use the dominant phenotype to name the alleles.
2. Step 2: Calculate q. The number of homozygous recessive individuals is q.
3. Step 3: Calculate p. Once you have q, finding p is easy!
4. Step 4: Use p and q to calculate the remaining genotypes. I always suggest that you calculate q.

How do you use the Hardy-Weinberg principle?

The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where ‘p2’ represents the frequency of the homozygous dominant genotype (AA), ‘2pq’ the frequency of the heterozygous genotype (Aa) and ‘q2’ the frequency of the homozygous recessive genotype (aa).

What do p and q represent in Hardy-Weinberg?

where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population.

What does the Hardy-Weinberg equation allow us to predict?

The Hardy-Weinberg equation allows us to predict which ones they are. Since p = 1 – q and q is known, it is possible to calculate p as well. Knowing p and q, it is a simple matter to plug these values into the Hardy-Weinberg equation (p² + 2pq + q² = 1).

How do you find the allele frequency of a next generation?

The frequency of A alleles is p2 + pq, which equals p2 + p (1 — p) = p2 + p — p2 = p ; that is, p stays the same from one generation to the next. The same can be shown for q.

What does the Hardy-Weinberg equation tell us?

The equation is an expression of the principle known as Hardy-Weinberg equilibrium, which states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

What do the following represent in the HW equation PQ p2 2pq q2?

The terms of this equation are defined as follows: p = the frequency of the dominant allele in a population. q = the frequency of the recessive allele in a population. 2 p q 2pq 2pq = the frequency of the heterozygous dominant genotype.
