What Is the Hardy-Weinberg Principle? - ThoughtCo

WebAs we will see below, the Hardy-Weinberg principle provides us with a mathematical equation to calculate the expected frequency of an allele in a population. P 2 + 2 PQ + Q 2 = 1. P: dominant homozygous frequency (AA) 2 PQ: heterozygous frequency (Aa) Q²: recessive homozygous frequency (aa) 1: 100% of the population. WebThe Hardy-Weinberg Principle The Hardy-Weinberg principle states that, if a population is not evolving, then the frequencies of alleles and genotypes in that population will remain constant from one generation to the next. Further, this principle allows us to predict what the genotype frequencies will be in a non-evolving population. We can conclude that a … WebWell let's revisit the Hardy-Weinberg equation. We've worked it out in a previous video, but I'll rewrite it right now. It says, the allele frequency for the dominant allele frequency squared, plus two times the dominant allele frequency times the recessive allele frequency, plus the recessive allele frequency squared, is equal to one. normal measurement of aorta
