Origins and migration
Where each strain emerged, and a line from every parent to its child, so you can follow how the genetics moved.
A marker sits at an approximate regional centre, never a precise location, and one marker can hold several strains. A line joins a parent's origin to its child's: it shows the link between them, not the route anyone travelled.
