Homolog genotypes of strains used for hapmap construction. Strains derived from a parasexual cross (Forche et al. 2008) contained homozygous (“aa” or “bb”) homologs for most or all of ChrR and Chr2–Chr7 and heterozygous trisomies (“aab” or “abb”) as indicated. Chromosomes indicated with “aab“ or “abb“ were trisomic; chromosomes designated “ab” were heterozygous along the entire length of the chromosome. Chromosomes indicated in color were informative for hapmap construction. Chr2 in strain P1 (**) was homozygous for each homolog along different sections of the chromosome. Color schemes for allelic fractions are consistent in Figures 1–4.
