# Hardy weinberg

The hardy–weinberg law was developed independently by an english mathematician, gh hardy, and a german doctor, wilhelm weinberg this concept is also known as the hardy–weinberg equilibrium, hardy–weinberg theorem or hardy–weinberg principle. The hardy-weinberg theorem states that the frequency of alleles and genotypes in a population’s gene pool remain constant over the generations unless acted upon by agents other than sexual recombination for example, take a population of mice that consists of 1,000 members a specific allele. The hardy-weinberg principle states that the genetic variation in a population stays constant over generations in the absence of disruptive factors the concept predicts that when mating occurs randomly in a vast population, the allele and genotype frequencies remain consistent because they are in. Paul andersen shows you how to solve simple hardy-weinberg problems he starts with a brief description of a gene pool and shows you how the formula is derived.

Hardy-weinberg equilibrium allele frequencies (or percentages, if you prefer) in a population will remain in hardy-weinberg equilibrium (hwe) from generation to generation if the following assumptions are met. The key to solving hardy-weinberg equilibrium problems is understanding the following equations: p + q = 1 (p + q)^2 = 1 p^2 + 2pq + q^2 = 1 hardy-weinberg equilibrium equations apply to an ideal situation: members of a large but completely isolated population mate at random no individuals enter or.

Hardy-weinberg equilibrium law states that allele and genotype frequencies in a population will remain constant from one generation to next generation in the absence of disturbing factors. This is where the hardy-weinberg principle comes in firstly, there are criteria for when this principle may be applied to a population: 1. From wikipedia, the free encyclopedia the hardy–weinberg principle states that both allele and genotype frequencies in a population remain constant--that is, they are in equilibrium--from generation to generation unless specific disturbing influences are.
