Genomic distribution of wild founder alleles in cultivated strawberry populations.(A) Heatmap displaying the relative contributions (dosages) of allelic diversity from wild octoploid progenitor species on chromosome 5 homoeologs in early hybrid, cosmopolitan, and California Fragaria × ananassa populations. Dosages were estimated from genetic distance ratios ($G_{Fc}/G_{Fv}$) in nonoverlapping 10 kb windows, where $G_{Fc}$ is the genetic distance between Fragaria × ananassa and F. chiloensis and $G_{Fv}$ is the genetic distance between Fragaria × ananassa and F. virginiana. (B) Kernel density plot displaying the distribution of $G_{Fc}/G_{Fv}$ ratios (allele dosages) estimated in nonoverlapping 10 kb windows across the octoploid genome in early hybrid, cosmopolitan, and California Fragaria × ananassa populations.
