Are baculum size and allometry a response to post-copulatory sexual selection in promiscuous males of the house mouse?

Great genital variation occurs across animal species, likely reflecting the operation of sexual selection. We quantified bacular, testicular, and vesicular size, variation, and allometry in house mice (Laurentii in: Mus musculus Linnaeus, Systema naturae 10th ed, Salvii, Stockholm, 1758) from the western Carpathians (Slovakia). We investigated whether baculum size is related to size of reproductive organs (testicular length and width, and...
