Table 2 Cumulative linked mixed models with fixed effects of litter type (same- versus mixed-sex) and sex on MatScore behaviours on neonatal marmosets (i.e., postnatal day 01). The sex composition of the litters did not impact behavioural performance on any of the assays in this procedure. Statistically significant differences are indicated in bold.
