Swedish research, a bi-product of building a database of genes from
all dog-races of the world, has concluded that dogs inherit from
four female wolves 100-130 kya. One of these is the ancestor of one
single dog-race (swedish jamthund), so all other races share
the other three ancestors. Mitocondrial dna was the base for this,
that is why inheritance on the female side is known only.
