From: Maternal control of visceral asymmetry evolution in Astyanax cavefish
The influence of maternal genetic effects on heart L-R asymmetry. (A) Reciprocal crosses between surface fish (SF) and cavefish (CF) gametes in both directions were used to assay for maternal genetic effects. (B) Bar graphs showing the percentage of heart looping types in the F1 progeny of CF × CF (top row), CF female × SF male (second from top row), SF female × CF male (second from bottom row), and SF × SF (bottom row) crosses. The number of larvae analyzed are indicated at the right of each bar. Blue asterisk: Chi2 statistic (all crosses) = 26.7158; p = .000164. Red asterisk. Chi2 statistic (CF × CF and CF × SF crosses) = 7.007; p = .030091.
