Fig. 2

Genetic variation in the draft genome assembly of O. felineus. Genome coverage (a) and K-mer frequency distribution (b) by paired-end library prepared from single-worm sample are presented. The plots demonstrate high heterozygosity level of the sample. Major peak (homozygous genome fraction, k-mers common to both haplotypes) is supplemented with the minor one at twice lower coverage corresponding to the k-mers associated with polymorphisms. c. Distribution of SNP density throughout the genome. In addition to the two major haplotypes of sequenced individual, two minor haplotypes (up to 9% each), possibly originating from the genetic material of a sexual partner, were also observed. Genomic scaffolds were arranged by their length as shown in the bottom panel, and densities were calculated in 500-kb windows. d. Boxplot of SNP density in genomic and coding regions
