A, Sequence variation within array of genes encoding tRNAleu (AAG anticodon) on Chr9. The genotype of each copy (ellipses) is color-coded according to the sequences in the alignment, in which bases diverging from the genome-wide consensus are colored. The hashmark on the chromosome represents a gap in the assembly. B, same as panel A but showing genes encoding tRNAmet (CAT anticodon) on Chr8 and Chr12. C, same as panel A but for a representative portion of the array encoding tRNAtrp (CCA anticodon) on Chr1. As illustrated below the chromosome, this tRNA occurs as part of a trimeric repeat encoding tRNAser, tRNAtrp, tRNAthr. Variation within the ser- and thr tRNAs is not shown.
