Means and Standard errors (SE) for Number of spots on the head, Spot size and Spot length in the <i>E</i>. <i>angramainyu</i> (P_A), <i>E</i>. <i>macularius</i> (P_M), and their F₁ and B_1M hybrids.

Number of spots on the head—square root transformed, Spot size—area of the largest spot scaled to the head size and natural log-transformed, and Spot length—length of the largest spot scaled to the head length and natural log-transformed. In the case of the Number of spots, post hoc Tukey tests at P < 0.05 were significant for all comparisons. The same procedure revealed two homogenous groups (E. angramainyu and F1; E. macularius and B1M) for the Spot area and Spot length. N–number of animals in the testing group.
