Table 2.
The probabilities of transition to the next courtship step are shown below for parental and hybrid males. Probabilities are the numbers of males performing the current step/ the number of males who performed the previous step. Also shown are Fisher Exact Tests to determine if the four types of males differed in their abilities to complete the courtship step with a particular type female. (Bonferroni correction, alpha = 0.05, p-values of 0.0083 or less are significant).
