Enrichment for rare CNV/PAV in teosinte genotypes. (A) The number of genotypes containing each was determined and the percent of events was plotted. Only 10% of structural variants are detected in one or two genotypes, while over 60% of structural variant events are detected in at least six genotypes. (B) The plot shows the allele frequency distribution for structural variant events in teosinte (black) and maize (gray). The proportion of DownCNV/PAV that are observed in one to 16 genotypes is shown. Teosinte has an excess of DownCNV/PAV observed in a single genotype relative to maize genotypes. (C) A similar plot is shown illustrating the distribution of allele frequency for UpCNV in maize (gray) and teosinte (black) genotypes.
