Distance matrix trees for specific OR subfamilies in human and chimpanzee. The first letter of the OR name indicate the species name (H and C for human and chimpanzee, respectively). Human OR sequence H5U512 was used as an outgroup in all cases. (A) Subfamily 4C: 20 human sequences (10 intact) and 27 chimpanzee sequences (12 intact) (B) Subfamily 2A: 14 human sequences (nine intact) and nine chimpanzee sequences (seven intact) (C) Subfamily 4F: 16 human sequences (nine intact) and 11 chimpanzee sequences (four intact) (D) Subfamily 6C: 17 human sequences (10 intact) and nine chimpanzee sequences (seven intact).
