Comparison between morphological and behavioral traits within F2 hybrid offspring. (a) Heat map of the correlations between morphological and behavioral traits in F2 offspring (R 2 values shown). (b) Total distance is significantly greater in albino (A) than in pigmented (P) individuals (t‐test: t 121 = 2.452, p < .0157). (c) Time in the center does not differ between pigmented and albino individuals (t‐test: t121 = 0.8957, p < .3722). For each trait, the median (center line) as well as 25th and 75th percentiles (dotted lines) are shown. (d) Standard length and angular speed are significantly correlated in F2 hybrid individuals (R 2 = 0.1989). (e) There is a significant association between peak angle and head length in F2 individuals (R 2 = 0.1072). Albino individuals are depicted as red squares, while pigmented individuals are depicted as black circles. **denotes p < .01. [Color figure can be viewed at wileyonlinelibrary.com]
