FIG. 6.

Inferred phylogeny for ASLV hosts in the avian order Galliformes based on MP analyses of 2,075 characters (703 informative sites) from the mitochondrial 12S rDNA and ND2 genes, with a waterfowl species (Aythya americana, redhead) as the outgroup. See Table 1 for bird species common names and corresponding ASLV names. Numbers on branches are bootstrap values based on 100 replicate searches and decay indices, respectively. Underlined host taxa were negative for retrovirus infection using our PCR primers.
