Question

You are breeding geckos and hoping to get a large percentage of female geckos. Your incubator has not been properly calibrated, so when you set the temperature to 78 °F it is actually 83 °F inside the incubator. Will this error cause you to have fewer female geckos than you would expect?

Answer 1

The gender of leopard geckos can vary depending on the temperature they were incubated in.
For example:
Incubating at 80 to 85 degrees will produce females.
Incubating at 90 to 95 will produce males.
Incubating anywhere in the middle will produce a mix of genders in your gecko population.
