Allele Count Total
Count total allele copies at a diploid locus as twice the number of individuals.
Description
Count total allele copies at a diploid locus as twice the number of individuals.
Allele Count Total applies one documented biological calculation to the values you provide. Count total allele copies at a diploid locus as twice the number of individuals.1
When to use Allele Count Total
Use this population- or quantitative-genetics calculation when genotype counts, variance components, pedigree relationships, and ploidy follow the definitions assumed by the tool.
- Individuals
- An integer count greater than or equal to 0.
How Allele Count Total calculates the result
The implementation follows this calculation rule: Count total allele copies at a diploid locus as twice the number of individuals.1
- Allele copies
- The calculated allele copies.
Limitations of Allele Count Total
Allele frequencies and genetic parameters describe the sampled population and model. Population structure, relatedness, selection, genotyping error, non-random mating, environmental covariance, and omitted variance components can bias interpretation. Preserve the input values and units so the result can be audited and recalculated.
Alternative or Complementary measurements
Inspect genotype counts and Hardy–Weinberg diagnostics, or fit a pedigree/genomic mixed model when individual records are available. Confidence intervals and replication across populations are more informative than a point estimate alone.
