  • Average nucleotide diversities (uncorrected P-distances; Swofford 2000) are shown. Length ranges are the minimum and maximum length of the given exon/intron for the sequences used in each species. Values for A. lyrata are based on five Aly13 subtypes. Intron 1, intron 2, and the first 9 bp of exon 3 are unalignable among the Aly13 subtypes and were excluded from the analysis. Exon values for Brassica are based on 16 SRK alleles from B. rapa and B. oleracea (13 Class I and 3 Class II alleles), and intron values are based on 4 SRK alleles (all Class I).

  • a The last 58 bp were excluded in calculations because 13-3 and 13-9 sequences ended there.
