How to do Hardy Weinberg Problems in Biology or AP Biology - SIMPLE

Struggling with Hardy Weinberg? Need a quick refresher on how Hardy Weinberg equations work? What is the point of the Hardy Weinberg Equilibrium? In this video I'll show you how to do a Hardy Weinberg practice problem for your Biology or AP Biology class. Use these notes to help you as you follow along with the video: Hardy Weinberg equilibrium as a model for describing and predicting allele frequencies in non-evolving populations. Hardy Weinberg represents “ideal” conditions for a population that is not changing. Natural populations DO change, so Hardy Weinberg provides a baseline to gauge the degree of change. Here are the two Hardy Weinberg Equations: p + q = 1 p2 + 2pq + q2 = 1 p = frequency of dominant alleles in the population q = frequency of recessive alleles in the population p2 = frequency of homozygous dominant genotypes in the population 2pq = frequency of heterozygotes in the population q2 = frequency of homozygous recessive genotypes in the population 00:00 What is Hardy Weinberg? 00:51 Hardy Weinberg Key 01:39 Practice Problem #1 03:09 Practice Problem #2 AP® is a trademark owned by the College Board, which is not affiliated with and does not endorse this video.
