From: Genomic ancestry estimation quantifies use of wild species in grape breeding
PCA-based ancestry estimation using 2482 SNPs and 56 indels for 7 wild Vitis, 7 V. vinifera, and 64 hybrid samples. a PCs were generated using wild Vitis and V. vinifera samples. The proportion of the variance explained by each PC is shown in parentheses along each axis. Hybrids were projected onto the axes. b Boxplots of PC1 values for wild Vitis, V. vinifera, and hybrid cultivars as well as a visual description of the calculation used for ancestry estimation.
