Figure 3

Bar chart showing the regression slopes of offspring length on parent length. Dam-offspring (dark bars) and sire-offspring (light bars) regression slopes are shown at hatching, yolk sac resorption stage and 15 weeks after exogenous feeding. The significant slopes are indicated with the following code: ***P-value <0.001, **P-value <0.01 or *P-value <0.05. A significant positive slope corresponds to positive correlation of parent and offspring lengths, while a significant negative slope corresponds to negative correlation between parent and offspring lengths. (a) Parent-offspring correlation slope for L♀D♂ hybrids. (b) Parent-offspring correlation slope for D♀L♂ hybrids. (c) Parent-offspring correlation slope for L♀R♂ hybrids. (d) Parent-offspring correlation slope for R♀L♂ hybrids.
