Cladogram with 131 hsYb9 and 16 Yb8 elements constructed by the neighbour joining method. Alu Yb9 and Yb8 elements are shown in blue and green, respectively. There is one Yb8a1 element in the cluster that matches best with one of the Yb9 elements, shown in red. The Yb8 copy shown in bold green is likely to be the source of all Yb9 copies in the cladogram. The Yb8 consensus (root) is shown in black.
