The heritability of personality factors in chimpanzees (Pan troglodytes)

摘要: Human personality and behavior genetic studies have resulted in a growing consensus that five heritable factors account for most variance human personality. Prior research showed chimpanzee is composed of dominance-related factor human-like factors—Surgency, Dependability, Emotional Stability, Agreeableness, Openness. Genetic, shared zoo, nonshared environmental components the six were estimated by regressing squared phenotypic differences all possible pairs chimpanzees onto 1 − Rij, where Rij equals degree relationship variable indicating whether pair was housed same zoo. Dominance significant narrow-sense heritability. Shared zoo effects accounted only negligible proportion factors.
