Table 4

The number of eggs, percent cleavage, neurulation and swim-up during the fertile period (11.5–17.5 hrs post-induction) for Bufo baxteri having received either one or two primings. In this table, the mean number of eggs, percent cleavage, neurulation and swim-up are based only on toads that produced eggs. Data are expressed as means ± SE. A significant difference was found for egg numbers, percent neurulation and swim-up, but not for percent cleavage between the two treatment groups.
