Female house mice avoid fertilization by t haplotype incompatible males in a mate choice experiment.

Manser A, König B, Lindholm AK - J. Evol. Biol. (2014)

Bottom Line: This approach enabled us to analyse female behaviour during the testing period, and the resulting paternity success and fitness consequences of a given choice.We show that genetic incompatibilities arising from the t haplotype had severe indirect fitness consequences and t females avoided fertilization by t incompatible males.The results are inconclusive whether this avoidance of t fertilization by t females was caused by pre- or post-copulatory processes.

Litter sizes ± standard errors of the mean (SEM) as a function of mother genotype (two panels) and the paternity of the litter, that is the genotype of the genetic father of the litter (either exclusively w, exclusively t, or both). The surface of the circles is proportional to the number of observations.

fig02: Litter sizes ± standard errors of the mean (SEM) as a function of mother genotype (two panels) and the paternity of the litter, that is the genotype of the genetic father of the litter (either exclusively w, exclusively t, or both). The surface of the circles is proportional to the number of observations.

Mentions: 34 of 83 mate choice tests (41%) resulted in offspring. Average litter size was 6.11 ± 2.21 (mean ± SD). In t females, litter sizes were significantly lower when mating with a t male than a w male (95% CI for difference between t and w sired litters: [1.24,5.94], z = 2.17, P = 0.030; see Fig. 2). Multiply sired litters on the other hand were not reduced in litter sizes (95% CI for difference between w and multiply sired litters: [−2.04,2.83], z = 0.63, P = 0.528). In w females, litter sizes were also smaller when t sired, but this was not statistically significant (95% CI w vs. t sired: [−0.76,4.11], z = 1.52, P = 0.129; 95% CI w vs. multiply sired: [−4.43,2.55], z = −0.10, P = 0.922).
