Comparison of expected sampling errors and experimental errors of the frequencies for the two alleles of SNP HBB28. The chart was drawn based on the results in Table 3. (a) The solid line is the expected sampling error for SNP site (HBB28) for the allele frequency of 0.05 for sample size up to 1000. The upper broken line is the estimated combine sampling and measurement error for this method based on Table 3 (see text). The lower broken line is measurement error. (b) The same as (a) for the allele frequency of 0.10 described in Table 3.
