Mother grooming of offspring and non-offspring in post-conflict versus non-conflict intervals from Limited evidence for third-party affiliation during development in wild chimpanzees (<i>Pan troglodytes schweinfurthii</i>)

Histogram of 10,000 proportions of non-conflict intervals in which mothers groomed A) offspring and B) non-offspring. PC = Average proportion of PC intervals in which an offspring or non-offspring was groomed. NC = Bootstrapped mean of proportions in which an offspring or non-offspring was groomed in a random non-conflict interval.
