According to the formula p² + 2pq + q² = 1, the sum of all possible allele frequencies is equal to 1. This is because when combining p and q together they represent all alleles in a given population, which is equal to 1. What is an example of allele frequency? Allele frequency...
Reported frequency in the last two rows of markers and genes are the calculated haplotype frequency for the wild donor parent in the population. The marker and gene-based haplotype calculation is illustrated in the methods section. The figure should only illustrate the model of SNP information ...
Filtering AF was previously defined as the threshold disease-specific “maximum credible AF” at or below which the disease could not plausibly be caused by that variant14. Filtering AFs were computed using the “inverse AF” calculator of a web-based tool (http://cardiodb.org/allelefrequencyap...
However, the formula for var(WiZi) varies for different pedigree structures and can be very complicated; it also depends on the unknown frequency p of allele A. Instead, we choose to estimate var(WiZi) empirically. Since var(Zi)=1, if Wi were a constant, var(WiZi) would be W2i. This...
For assessing monoallelic expression status of the candidate imprinted genes, we first sequenced DNA of exons containing high frequency SNPs (based on dbSNP) for genes listed in Tables2and3. Once heterozygous samples were identified, we tested whether the gene was monoallelically expressed. ...

calculated based on the SNP genotypes of each accession. The nucleotide diversity level,π, was calculated using the method mentioned above. Sliding 20-kb windows were used during the calculation with a 2-kb sliding step. ROD was computed using the formula, ROD=(πirrigated−πupland)/π...
Take the root of q² to determine the allele frequency of the mutated allele, which is 0.1. Subtract this value from 1, which is the total allele frequency, in order to obtain the value of p. This calculation is based on the Hardy-Weinberg equation for allele frequency: p + q = 1...
(‘Allele proportion’ would perhaps be a more precise term than ‘allele frequency’, but I will stick to the latter expression used traditionally in population genetics.) More generally, the calculation of AFD between two populations at a genetic polymorphism can be formalized as 𝐴𝐹𝐷=...
