A simple tally of genes that support alternative hypotheses.

Hu = Human (Homo sapiens), Fr = Western Clawed Frog (Xenopus tropicalis), ZF = Zebra Finch (Taeniopygia guttata), Ch = Chicken (Gallus gallus), An = Green Anole (Anolis carolinensis), PT = Chinese Pond Turtle (Mauremys reevesii), ST = Soft-shelled Turtle (Pelodiscus sinensis), Py = Royal Python (Python regius), Tu = Tuatara (Sphenodon punctatus), Op = Opossum (Monodelphis domestica), Cr = Nile Crocodile (Crocodylus niloticus). For example, the clade ((ZF,Ch),PT) appears on 2117 gene trees without regarding other relationships. The 7-species dataset includes 4,584 putatively orthologous proteins and coding genes; the 11-species dataset includes 1,638 putatively orthologous proteins and coding genes.
