Percent heterozygosity and allele dosage frequency distributions. Percent heterozygosity was determined with 6373 SNP markers and a diploid genotyping model. Allele dosage frequencies were determined with 3763 SNP markers and a dosage genotyping model. (A) Distribution of percent heterozygosity across the 250 lines in the diversity panel. (B) Histogram of percent heterozygosity in cultivated potato vs. all of the wild species and genetic stocks. (C) Histogram of percent heterozygosity in diploid vs. tetraploid lines. (D) Percent heterozygosity in wild species individuals. (E) Distribution of average percent allele dosage frequencies within each market classes for tetraploid lines only. (F) Proportion of allele dosage frequencies within individual released lines by release year for tetraploid lines only.
