Well, for the mitochondrial data set that comes with PAUP, a simple analysis
gives shared advances states as:
Homo-Pan 19
Homo-Gorilla 11
Gorilla-Pan 14

This is not informative by nonparametric tests at, say, 95% reliability.
Satta et al. reviewed molecular studies and found, of 45 loci:
Homo-Pan 23
Homo-Gorilla 8
Gorilla-Pan 8
Homo-Gorilla-Pan 6

This is informative, and the Mr. Chimp is apparently our brother.
I reviewed this in Syst. Biol. 50: 425-437, 2001.

The proportion of 36/14/17 does not constitute separate categories, so a
calculation of reliability cannot be done.
