Alleles of midrepeat sequences for genes in the ALS and HYR families. For each of 43 C. albicans isolates, the number of sequence repeats (shown on the y axis) is indicated by a line joining the repeat numbers for the two alleles of each gene. A horizontal line thus indicates homozygous repeats of the numbers indicated in the y axis. A diagonal line indicates an isolate with heterozygous repeats, with the larger of the two allele repeats indicated by the left-hand position of the line. For isolates with identical allele pairs, the results have been jittered vertically to make each isolate line visible. The isolate data are grouped in columns representing results for isolates in clades 1, 2, 3, and 4. Note that some y axes have been compressed to emphasize interclade differences.
