Table 4. Correlations between identity and spacer size for CDR.

^a24 chromosomes with more than 20 two-copy CDR were used to test correlations.

^bAbbreviations are those used in Table 1.

^cCoefficients of Kendall τ rank tests between spacer size and identity for CDR.

^dProbability associated with the Kendall τ rank tests. We assumed that, at an α risk of 0.01, 18/24 correlations are significant (with a risk of 0.21 of getting at least one false positive and of 0.02 of getting at least two false positives).

^eWe used two-copy; three-copy, four-copy and five-copy CDR to test 17 new chromosomes and re-test the six non-significant ones, where the two-copy CDR were less than 20 or were the tested correlation was P < 0.01.

^fProbability associated with the Kendall τ rank tests. We assumed that, at an α risk of 0.01, 15/23 correlations are significant (with a risk of 0.21 of getting at least one false positive and of 0.02 of getting at least two false positives).
