Table 2 Results of a beta-binomial mixed model for effect of baculum morphometrics of the second male on his fertilization success relative to the first male (P2), including interactions with plug removal treatment, body mass of the second-to-mate male and genotype as covariates

From: The baculum affects paternity success of first but not second males in house mouse sperm competition
