The nucleotide associated with each allele is shown in brackets. For each marker, the number of varieties in each allelic category is shown, and the mean for each category (with standard error of the mean shown in brackets). The t-statistic for the comparison of the two alleles is shown also, along with the p-value for the right tail of the t-distribution (testing the hypothesis that the mean of the high allele is greater than that of the low allele). Variation in the total number of lines between markers is due to missing data.
