Anatomical females carry a Y chromosome only rarely, as a result of genetic defect.

The other linkage group is the mitochondrial DNA (mt DNA).

When looking between distantly related species, recombination is less of a problem since recombination between branches from common ancestors is prevented after true speciation occurs.
