a
The results show the current vocalization threshold differences (p value) comparing a given group with the respective reference group. Intercept indicates the intercept coefficient of the regression model, i.e. the value at which the fitted line in the model crosses the y-axis. – indicates the reference group, hetero indicates heterozygous, homo homozygous, young indicates age < 10 weeks, middle 12 < age < 16 weeks, and older 20 < age < 27 weeks. R2 indicates R square.
