    Male/female expectations
    I was just wondering how it all worked. If it was a 50/50 chance or more based off of incubator conditions like some species were at x temp youll get more males and at y temp youll get more females.

    Hi,

    Just 50/50 per egg I'm afraid.

    The chances are 50/50. While those are the chances, I have been very lop sided for the last three years. Three years ago, I was about 65/35 M/F, then the following year I was about 30/70 and last year, I was back to about 60/40. I think if you look at a large enough number, then it will be 50/50, but smaller sampling sizes can vary quite a bit. Heck I have hatched entire clutches of one sex.

    The report is that snake gender is chromosome determined. However, rather than the mammal xy system they have a zw system like birds. Females are zw and males are zz. So it's the female that determines gender by giving either a z or a w which is the opposite of mammals where the male determines gender by giving x or y. You never know though there still could be environmental or individual factors to which chromosome a particular female gives more in a particular breeding.
