Extended Data Fig. 1: Chromosome-scale selective sweeps across wild C. elegans isotypes.
From: Balancing selection maintains hyper-divergent haplotypes in Caenorhabditis elegans
a, The genome-wide distribution of the most frequent haplotype (red) among 324 wild isotypes with known geographic origin is shown. Grey genomic regions represent other haplotypes, and white represents unclassified haplotypes. Each row is one of the 324 isotypes, grouped by the geographic origin. The genomic position in Mb is plotted on the x-axis, and each tick mark represents 5 Mb of the chromosome. b, Beeswarm plots of the proportion of the most frequent haplotype for each chromosome from (a) for 324 isotypes with known geographic origins are shown. Wild isotypes are grouped by geographic origin. Each point corresponds to one of the 324 isotypes, and geographic origins are shown on the y-axis.
