橡樹基因組分析 GENOMIC IDENTITY OF WHITEOAK SPECIES IN AN EASTERNNORTH AMERICANSYNGAMEON

Figure 6.  The white oak syngameon of eastern North America sensu Hardin (1975), including only the species investigated inthe current study. The figure replicates the 16-species figure of Hardin (1975: fig. 1), including only the subset of seven species weinvestigated in the current study (treatingQuercus muehlenbergiiEngelm. andQ. prinoidesWilld. as one), with lines indicatinghybridizations that Hardin inferred from morphological study. Thin-dashed lines indicate hybridizations identified by Hardin butnot by us; medium-dashed lines were identified by both Hardin and us, at an admixture level of 0.10 to 0.19 for at least onespecimen; and thick-dashed lines indicate admixture levels of 0.20 or higher for at least one specimen.
