Behavioral genetic research on tolerance in Japanese macaques

日本猕猴（Macaca fuscata）生活在等级森严的社会中，地位高的猴子会攻击下属，以独占食物。攻击性行为频率的区域差异是有据可查的。我发现，胜山组（日本冈山县马尼瓦市）和淡路岛组（日本兵库县洲本市）之间的这些区域差异与野生日本猕猴中两个攻击相关候选基因的频率有关。

Japanese macaques (Macaca fuscata) live in highly hierarchical societies and high-ranking monkeys attack subordinates so as to monopolize provisions. Regional differences in the frequency of aggressive behavior are well-documented. I found that these regional differences between the Katsuyama group (Maniwa city Okayama prefecture, Japan) and Awajishima group (Sumoto city Hyogo prefecture, Japan) were associated with frequencies of two aggression-related candidate genes in wild Japanese macaques.
