[i] Detection from complementary strand.

[ii] Data from ten samples of each genotype was used, except for the fluorometric measurements of M9 C allele, SRY10831 G allele and M17 T allele where only five samples were used.

[iii] The range of variation between the lowest and highest R values.

[iv] Raverage of alleles1/Raverage of alleles2.
