“Reconciled” trees using complete repeats of FLG in human, chimpanzee, gorilla, orangutan, and crab-eating macaque. a “Reconciled” gene tree indicating duplication (red squares) and loss events (light gray italics) from the most common ancestor of these primates: the crab-eating macaque repeats duplicated 11 times, orangutan repeats duplicated 8 times, and gorilla/chimpanzee/human repeats duplicated 18 times, and in human, the counterpart to chimpanzee-repeat 9 was lost, while in chimpanzee, the counterparts to human-repeats 10 and 8 were lost, and in gorilla, the counterpart to human-repeat 2, 9 and 8 and chimpanzee-repeat 8 was lost. b “Reconciled” species tree indicating duplication and loss events in each species from their most common ancestor: crab-eating macaque repeats duplicated 11 times, orangutan repeats duplicated 8 times, gorilla repeats duplicated 6 times, and chimpanzee repeats duplicated 3 times, while the most common ancestor between human and chimpanzee duplicated 6 times, and the most common ancestor between human, chimpanzee, and gorilla duplicated 4 times; and 1 repeat was lost in gorilla, 2 repeats were lost in chimpanzee, and 1 repeat was lost in human. The number of repeats found in each species is provided in parentheses
