extremely significantP = 0.0001
There was an extremely significant difference in the number of male offspring among the four crossings (SNK, P = 0.0001), though no significant difference was observed between (WT♀ × WT♂) (53.56 ± 2.49) and (TI♀ × TI♂) (58.35 ± 1.89) (SNK, P = 0.074), both of which gave approximately equal mean number of male and female progenies ( Table 1 ).
