Genotype and growth rate influence female mate preference in Xiphophorus multilineatus: Potential selection to optimize mortality-growth rate tradeoff

The extent to which mate preferences are adaptive requires a better understanding of the factors that influence variation in mate preferences. Xiphophorus multilineatus is a live-bearing fish with males that exhibit alternative reproductive tactics (courter/sneaker). We examined the influence of a f...

description The extent to which mate preferences are adaptive requires a better understanding of the factors that influence variation in mate preferences. Xiphophorus multilineatus is a live-bearing fish with males that exhibit alternative reproductive tactics (courter/sneaker). We examined the influence of a female’s genotype (courter vs sneaker lineage), growth rate, and social experience on mate preference for courter as compared to sneaker males. We found that females with a sneaker genotype and slower growth rates had stronger mate preferences for the faster growing courter males than females with a courter genotype, regardless of mating experience with one or both types of males. In addition, the relationship between strength of preference and growth rate depended on a females’ genotype; females with sneaker genotypes decreased their preference as their growth rates increased, a pattern that trended in the opposite direction for females from the courter genotypes. Disassortative mating preferences are predicted to evolve when heterozygous offspring benefit from increased fitness. Given male tactical dimorphism in growth rates and a mortality-growth rate tradeoff previously detected in this species, the variation in mating preferences for the male tactics we detected may be under selection to optimize the mortality-growth rate tradeoff for offspring.
