Test of balanced meiotic transmission of alleles from both parental species (On for O. niloticus and Sm for S. melanotheron) for each of the 8 hybrid F1 breeders (G1 (♀ On × ♂ Sm) and G′1 (♀ Sm × ♂ On)); Chi² values and associate -values are given; significant (i.e., biased transmission) tests () when applying sequential Bonferroni correction ( = independent tests) are indicated in bold.
