-
Each cell represents the observed numbers of matched and mismatched bases for nucleotide positions aligned in intergenic, intronic, and total conserved blocks. Rounded frequencies of observations are in parentheses and are scaled relative to intergenic (20,499), intronic (9,414), or grand (29,913) totals, which do not include ambiguous nucleotides.
-
↵Significant differences between reciprocal substitutions atP < 0.05/18 = 0.00278.
