Maximum plotted = 300, minimum plotted = 80</p> <p>7 (pink line plot) - GC percent. Black line = 50% GC, light grey area = 50% - 30 % GC, dark grey area = > 30% GC. </p> <p>Maximum plotted = 60% GC, minimum plotted = 20% GC</p> <p>8 (green stacks) - Repeat Masker matches.</p> <p> </p> <p>The genome assembly contains numerous low GC, high coverage, repeat rich regions, with low overall gene density. This suggests an assembly with collapsed repeats.</p>
