allele frequencies in a population will remain constant unless one or more factors cause those frequencies to change
The Hardy Weinberg equation is: p2 + 2pq + q2 = 1 Where p and q are the initial frequencies for the two alleles in question. This equation suggests that the three possible genotypes (homozygous p, heterozygous pq, and homozygous q) will reach a frequency equilibrium (i.e. stable frequency) in those proportions described above, if the following conditions are met: # Large population # No mutation # No selection# No emigration/immigration # Random mating In other words, evolution-- allelic frequency change within a population-- will not occur if the above 5 conditions are met.
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 introduced. In practice, however, it is impossible to remove such disturbing influences thus making this principle purely theoretical.
The Hardy Weinberg theorem suggests genetic equilibrium. The probability of offspring's genotype based on parents' genotype or the offspring's genotype can be used to reveal the parents.
how can i explain hardy weinberg's principle and how can i use it in different ways?

Genetic equilibrium is a theoretical concept used to study the dymamics of single alleles in the population gene pool. In practice, there is no situation in which allele frequencies do not drift to some degree. Large populations may slow drift down, but there will still be drift.
Genotype frequencies in a population.
Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
Hardy-Weinberg equilibrium
The Hardy-Weinberg equation is as follows: p2 + 2pq + q2 = 1 p & q represent the frequencies for each allele.
Hardy-Weinberg Principle.
No statements, but a few of the Hardy-Weinberg conditions. Random mating. No gene flow. No natural selection.
p is the value of an allele frequency.

Hardy and Weinberg wanted to answer the question of how genetic variation is maintained in a population over time. They developed the Hardy-Weinberg equilibrium principle, which describes the expected frequencies of alleles in a population that is not undergoing any evolutionary changes.
The evolutionary influences present in the Hardyâ??Weinberg principle are mate choice, mutation, selection, genetic drift, gene flow and meiotic drive.
The Hardy Weinberg Principle states that a trait that is neither selected for or against will remain at the same frequency in the population. Therefore, traits in a population that are neither selected for or against are in equillibrium and remain in the population at a steady state.

The Hardy-Weinberg principle is a bit like the "Punnett square for populations". A Punnett square can predict the probability of offspring's genotype based on parents' genotype, or the offsprings' genotype can be used to reveal the parents' genotype. The Hardy-Weinberg principle can be used to calculate the frequency of particular alleles based on frequency diseases. This principle can determine useful but difficult-to-measure facts about a population.
