|Distribution of multiple rDNA sites in genera having species with single sites restricted to only one chromosome region|
|Number of genera with multiple sites|
|Position of single sites||Number of genera with single sitesa||In any region||In the same region||p-valueb|
a Genera having species with single sites in one position and other species with single sites in a different position were excluded from this sample.
b Comparisons with terminal region (Fisher’s exact test), n.s. non-significant.
