Figure 4.
Relationship between behavioral traits within F2 hybrids. (a) Schematic for behavioral analysis where individual F2 fish were tested for locomotor activity, escape reflex, and then prey capture in succession. (b) Heat map of the correlations between behavioral traits in F2 offspring (R 2 values shown). (c) Peak angle of the escape reflex is associated with angular speed (F 1,45 = 17.31, p < .0001). (d) Peak angle during the escape reflex is not associated with feeding strike angle (F 1,44 = 0.0231, p < .8799). Albino individuals are depicted as red squares, while pigmented individuals are depicted as black circles. [Color figure can be viewed at wileyonlinelibrary.com]
