在红原鸡（Gallus gallus）的混合性别群体中，雄性和雌性都形成了统治等级，雄性-雄性攻击和雌性选择可以影响交配成功。如果雌性更喜欢占主导地位的雄性，那么在内性选择和间性选择之间就没有冲突。我们研究了由两只雄性和三只雌性组成的俘虏贝克。在1998年，占主导地位的男性有更大的梳子比下属男性在大多数羊群，而在1999年，梳子大小坚果之间的主导地位和下属男性不同。占主导地位的男性crowed更多，并进行更多的翼R：lps比下属男性，但这两个男性进行了同等数量的花絮和华尔兹。统治雄性比从属雄性获得更多的交配。当统治地位的男性有更大的梳子，女性的所有职级更愿意与占主导地位的男性交配和相关。当下属男性有较大的梳子，初级和二级女性交配的主导男性，而三级女性：交配更经常与下属男性，女性协会与男性没有预测交配。大梳子的男性是女性的首选，往往成为主导地位，但女性似乎更喜欢大梳子的男性，即使这些男性是下属。
In mixed-sex flocks of red jungle fowl (Gallus gallus), both males and females form dominance hierarchies, and male-male aggression and female choice can influence mating success. If females prefer the dominant male, there is no conflict between intra- and intersexual selection. We studied captive Becks consisting of two males and three females. In 1998, dominant males had larger combs than subordinate males in most flocks, while in 1999, comb size did nut differ between dominant and subordinate males. The dominant male crowed more and performed more wing R:lps than the subordinate male, but both males performed an equal number of tidbits and waltzes. The dominant male obtained more copulations than the subordinate male. When the dominant male had the larger comb, females of all ranks preferred to mate with and associated with the dominant male. When the subordinate male had the larger comb, primary and secondary females mated with the dominant male while tertiary females: mated more often with the subordinate male, and female association with a male did not predict mating. Males with large combs are preferred by females and tend to become dominant, but females seem to prefer males with large combs even when these males are subordinate.
