During evolution, different chromosome elements represented by the colored Lego bricks (NA, NB, NX..etc. in the figure) were added onto the ancestral sex chromosomes in different species, forming the great diversity of nematode sex chromosomes. These ‘Lego’ combinations of chromosome elements are shown as corresponding colors for each ‘clade’ of nematode species. (IMAGE)
