Fig. 1: Genome landscape and polymorphism analysis of the sea cucumber Apostichopus japonicus.
From: Sea cucumber genome provides insights into saponin biosynthesis and aestivation regulation
From outer to inner circles: I, marker distribution on 22 chromosomes at the Mb scale; II and III, single nucleotide polymorphism (SNP) density across genome (II) or CDS (III) drawn in 1-Mb sliding windows with a 50-kb step (yellow columns), and polymorphism hotspot regions (p < 1e–4) are colored red; IV and V, gene density and repeat density across the genome, respectively, drawn in 1-Mb non-overlapping windows
