|
A mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.
|
|
|
Always occurring within populations of organisms in nature.

|
|
Only useful in the lab and cannot be practically applied to real-world populations of organisms.

Detailed explanation-1: -It predicts how gene frequencies will be inherited from generation to generation given a specific set of assumptions. When a population meets all the Hardy-Weinberg conditions, it is said to be in Hardy-Weinberg equilibrium (HWE).
Detailed explanation-2: -Hardy-Weinberg Equilibrium (HWE) is used to estimate the number of homozygous and heterozygous variant carriers based on its allele frequency in populations that are not evolving.
Detailed explanation-3: -It states that in a gene pool the sum of all the allelic frequencies is 1. According to this principle, if the measured frequencies come out different from the expected frequencies then it depicts certain evolutionary changes.
Detailed explanation-4: -The Hardy-Weinberg model also serves a mathematical formula used to predict allele frequencies in a population at genetic equilibrium. If you know the allele frequencies of one generation, you can use this formula to predict the next generation.
