Document Summary
Scaling up from a single cross to a populaion. Introducion to populaion geneics and hardy weinberg equilibrium. How do we know whether evoluion is occurring (tesing for hardy. Interbreeding group of individuals that belong to the same species and live within a restricted geographical area. The frequency of an allele in a populaion is oten not the same as the raio in a single cross. What should our null hypothesis be for evolution? if evoluion is change in gene frequencies over ime, then null hypothesis should be no change in gene frequencies over ime. In 1908, gh hardy and w. weinberg used probability theory to solve this problem for 2 alleles at a single locus. The assumpions of their model considered a populaion with the following characterisics: a single locus with two alleles does not change state b/n generaions, i. e. , no mutaion. No new alleles arise in the populaion: alleles are not added to the populaion:
