Abstract: In small populations, mating behaviors that mitigate effects of inbreeding depression in offspring should be favored. Female iguanas on Little Cayman Island appear to produce more outbred offspring when they mate with outbred, unrelated, or multiple males. However, general patterns of relatedness among mates are most consistent with male competition dictating skewed reproductive success rather than inbreeding avoidance. These findings suggest that selection favoring female choice can be constrained by selection favoring male dominance.
