Fig. 3

Principal component analysis of three scaffold metrics for (A) coastal and (B) inland genome assemblies respectively (proportion of unmatched single-copy kmers, male-to-female ratio of mean scaffold mapped read depth, and male-to-female ratio of horizontal scaffold mapping coverage by WGS reads). Each dot in the plot represents one genomic scaffold, and colours correspond to the best map targets in the female Zebra Finch assembly bTaeGut2 (Teal: Chr1A; Beige: ChrW; Red: ChrZ; Grey: autosomes other than Chr1A). C, D Distribution of scaffolds along PC1 in each EYR assembly. Eigenvalues in histogram are aligned and correspond with respective PCAs above. Scaffolds in both lineages’ genome assemblies sort into a trimodal distribution along PC1.
