From: Population structure in diverse pepper (Capsicum spp.) accessions
Capsicum nucleotide diversity (π) calculated A genome wide by species and B chromosome-wide by species. C Scans of nucleotide diversity (π) across each chromosome of four species. Box plots show the median, box edges represent the first and third quartiles, and the whiskers extend to farthest data points within the 1.5 × interquartile range outside box edges
