Data from: Mito-nuclear discord in six congeneric lineages of Holarctic ducks (genus Anas)
Many species have Holarctic distributions that extend across Europe, Asia, and North America. Most genetics research on these species has examined only mitochondrial (mt) DNA, which has revealed wide variance in divergence between Old World (OW) and New World (NW) populations, ranging from shallow,...

Most genetics research on these species has examined only mitochondrial (mt) DNA, which has revealed wide variance in divergence between Old World (OW) and New World (NW) populations, ranging from shallow, unstructured genealogies to deeply divergent lineages.

Genetic differentiation for both marker types varied widely among these lineages (idiosyncratic population histories), but mtDNA and nuDNA divergence within lineages was not significantly correlated.

Many species have Holarctic distributions that extend across Europe, Asia, and North America.
