around 30. I forget the exact number. This was the largest, we were studying whether or not there is an effect on the sex of the gators being born with the warmer winters and heavy droughts we have had through the south. we found about a 60/40 split between sexes. I do not have access to the previous studies right now though so I am not sure if these results are significant or not. I will let you know when the final paper gets sent my way.
