The Hardy-Weinberg Principle and estimating allele frequencies in populations

Evolution involves changes in the gene pool. A population in Hardy-Weinberg equilibrium shows no change. What the law tells us is that populations are able to maintain a reservoir of variability so that if future conditions require it, the gene pool can change.

The Hardy-Weinberg Principle deals with the frequency, or percentage, of alleles in a population. It states that the frequency of an allele, or rather the number of times an allele is present in a population, 1. To investigate the Hardy-Weinberg Principle you will be working in a group with 3 other students.

If genotypes are in Hardy-Weinberg proportions, one or more of Assumptions #1-#8 may still be violated. Point (3) is why Hardy-Weinberg is so important. There isn't a population of anything anywhere in the world that satisfies all 8 assumptions, even for a single generation.

This never occurs in nature but helps to understand the forces of evolution. The frequency of genotypes in a population can be determined /described mathematically...

This definition of evolution was developed largely as a result of independent work in the early 20th century by Godfrey Hardy, an English mathematician, and Wilhelm Weinberg, a German physician. This has become known as the Hardy-Weinberg equilibrium equation. In this equation (p² + 2pq + q² = 1),

According to the Hardy-Weinberg Principle, the genetic makeup of a population remains constant from one generation to the next assuming five things do or do not occur.

The Hardy-Weinberg principle is based on the stipulation that there will be no change in allele frequency of a population over time.
