Lineage Sorting

LINEAGE SORTING. Eucalyptus globulus, Tasmanian blue gum.
Along the path from Campus Drive and Lausen to Arboretum and Galvez.
When one population diverges into two populations, each genetic lineage in the ancestral population becomes part of one but not the other of the descendant populations. This process by which a group of lineages separates into descendant populations at a population divergence is the process of lineage sorting—much like the sorting of strands of bark at branch points on this Tasmanian blue gum.
