Hardy’s paper was focused on debunking the then-commonly held view that a dominant allele would automatically tend to increase in frequency; today, confusion between dominance and selection is less common.
Note however, such a population cannot be tested for equilibrium using the significance tests below because it is assumed a priori. Please log in to add your comment.
Equilibri de Hardy-Weinberg
It can be shown that the other two equilibrium conditions imply the pey equation. Mendel’s laws and their probable relation to intra-racial heredity. Journal of Mathematical Biology 2 33 – 39 Edwards, A. From the Publisher via CrossRef no proxy periodicos. These recurrence relations follow from fundamental concepts in probability, specifically independenceand conditional probability.
Present to your audience. Hardy, Weinberg and language impediments. This uses a triangular plot also known as trilinear, weinerg or ternary plot to represent the distribution of the three genotype frequencies in relation to each other. Depending on whether the organism is a ‘true’ tetraploid or an amphidiploid will determine how long it will take for haardy population to reach Hardy—Weinberg equilibrium.

Equilibrium occurs when each proportion is constant between subsequent generations. In this way, the hypothesis of Hardy—Weinberg proportions is rejected if the number of heterozygotes is too large or too small.

The null hypothesis is that the population is in Hardy—Weinberg proportions, and the alternative hypothesis is that the population is not in Hardy—Weinberg proportions. The conditional probabilities for the heterozygote, given the allele frequencies are given in Emigh as. Biological Modeling in Philosophy of Biology.
Where the final equality holds because the allele proportions must sum to one. Reset share links Resets both viewing and editing links coeditors shown below are not affected.
Science Logic and Mathematics. Henryk Kotlarski – – Mathematical Logic Quarterly 51 4: Evolutionary Forces and the Hardy—Weinberg Equilibrium. Today, tests for Hardy-Weinberg genotype frequencies are used primarily to test for population stratification and other forms of non-random mating.
