Sample sizes by phenotype.
Fig 1.
PCA of ten phenotypes in wild (N = 79) and cultivated apples (N = 801).
A) PC1 vs PC2. B) PC1 vs PC3. The proportion of the variance explained by each PC is shown in parentheses on each axis. C) The difference between wild and cultivated apples for PCs 1, 2 and 3 are shown as violin plots. P values from a Wilcoxon test comparing PC values between cultivated and wild apples are shown for each of the first three PCs.
Fig 2.
Overlapping density plots of 10 phenotypes comparing values from wild and cultivated apples.
The phenotype associated with each plot is shown along the X axis. The W and Bonferroni-corrected p values report the results of performing a Wilcoxon rank sum test of the difference between the phenotypic distributions of wild and cultivated apples.
Fig 3.
Phenotype values of cultivated apples as a function of their release year with a comparison to values in their wild ancestor, M. sieversii.
Phenotypes include phenolic content (A), firmness change during storage (B), flowering date (C), and soluble solids (D). Values for cultivated apples are blue, and the values observed for M. sieversii are represented in yellow as a violin plot on the left side of each plot. The R and p values from a Pearson correlation between phenotypic values and release year are shown within each scatter plot.
