PAVs frequencies in maize genetic groups. a Hierarchical clustering of PAV frequency (F2 allele) within maize groups. Left: F2-present PAVs (typing of Presence variant). Right: B73-present PAVs (typing of Absence variant is shown). Horizontal lines represent PAVs. Vertical bars represent the four maize genetic groups. Light colors highlight low frequencies and strong colors indicate high frequencies of the F2 allele. b F2-present PAV frequency (left) or B73-present PAV frequency (right) within 2 genetic groups: Corn Belt Dent and European Flint. PAVs shared by F2 and a single genetic group (green) are separated from PAVs shared in at least one individual of the 4 genetic groups analyzed in this study (red). Left: sequences present in F2 and absent in B73. Right: sequences present in B73 and absent in F2
