Fig 2. A genome structure consistent with absence of meiosis.

Five pairs of duplicated homologous collinear regions co-occur on a same scaffold in M. incognita (A) and five in M. arenaria (B). All curves show connections between collinear gene pairs used by MCScanX to define duplicated regions (blue curves show tandem duplications and purple curves show palindromic duplications). Grey lines represent the gene density on the scaffolds.
