Figure 2. The duplicated Atlantic salmon genome.
Homeologous regions in the Atlantic salmon genome subdivided into 98 collinear blocks along the 29 European Atlantic salmon chromosomes. Red rectangles represent blocks of sequence without identifiable duplicated regions elsewhere in the genome. a, This track shows grouping of salmon sequence into regions; red = high (>95% sequence similarity), orange = elevated (90–95% sequence similarity), green = low (~87% sequence similarity), yellow = telomeric regions (10 Mb) characterized by highly elevated male recombination (see ref. 10). b, This track shows genomic similarity (in 1 Mb intervals) between duplicated regions (red = high, yellow = medium, green = low sequence similarity). c, Ths track shows frequency of Tc1-mariner transposon elements in the Atlantic salmon genome.
