3.1Genome size estimation and initial characterization of the genome
A total of 79 Gb of Illumina data werer generated from the Illumina 150 insert-size library, representing 143.64‐fold coverage of the burbot genome (Table 1, Supplementary Table S2). The total number of fk -mers was 62,863,455,719, with a k -mers peak at a depth of 112 (Supplementary Figure S1 and Table S3). The genome size was estimated to be ~550 Mb with heterozygosity of 0.57% and repeat content of 36.60% (Supplementary Table S3).
