  • The Dp values (above the diagonal) were calculated from the allelic frequencies at loci in chromosome regions with CE ≤ 0.5 or < 1.0, and Dd values (below the diagonal) were calculated from the allelic frequencies at loci in chromosome regions with CE ≥ 0.5 or > 1.0. ** indicate corresponding values above and below the diagonals that differed from each other at the 1% probability level (t-test).
