Q) If low temps produce dark colored albinos how can I produce light colored albino females?
A) Sex in leopard geckos is determined within the first 2-weeks of incubation. So if you let albino eggs experience 78-83F for 14-20 days (20 days is better to place it safe) that will lock in the female sex and then you merely move those female eggs to a constant 90F for the remainder of incubation to get the best looking possible female offspring.
