Note: The data in the table are the average values and standard errors of mixed samples of each group (n = 3). Different letters of (a, b, and c) indicate the significance of the three genotypes of zebrafish. Those with different letters are significant (p < 0.05), while those without letters are not significant (p > 0.05).
