Overview of variants found using nuclear capture probes when mapping putative whale shark reads to the whale shark genome (accession no. GCA_001642345.2) (a,b) and when mapping quality‐filtered, dereplicated raw reads to the Thunnus thynnus genome (accession no. GCA_003231725.1) (c,d). (a,c) The number of variant sites retained as depth filter (i.e., minimum coverage required for a variant to be retained) increases for both “all variants” and “polymorphic variants” (variants where both the reference allele and another allele are present in the data). (b,d) The relative percentage of polymorphic variants compared to total variants across the same depth filter gradient [Colour figure can be viewed at wileyonlinelibrary.com]
