Calculating the genotypic frequencies ofRR, Rr, rr in next generation based on allelic frequency of p = 0.8 and q =0.2. - frequencies of alleles in a gene pool if we know the frequency of genotypes or - the frequency of genotypes if we know the frequencies of alleles. Hardy-Weinberg Equilibrium Calculator. Update the values by changing the the allele frequency in the blue box below the graph. The calculator has a check that prevents the allele frequences from summing to any value other than 1. If a population has 10 alleles for a specific gene,

Calculating Allele Frequency Definitions. locus. The frequency of the O allele is 0.67 in the United States. A person’s blood is Rh+ if he or she is homozygous or heterozygous for the D allele at the Rh locus, which has an allele frequency of 0.6. Assuming no linkage disequilibrium between these two unlinked loci, what is the frequency of people with blood type O+, assuming, gene pool • Bottom line is differential reproductive success: some genotypes out reproduce others. Change in allele frequency depends on genotypic fitness • Why?, because selection acts on phenotypes not alleles Chapter5.ppt.pdf Author: Dave Gray.
