I'm not sure I understand what you're asking. For incubation? I could be wrong but I really don't think there is a hard and fast rule someone can give you.
Years ago! I read something about manipulating color by incresing the temps in the final stage of incubation¡ (this was in the Tremper book) but i forgot details...
Incubation: Once you have your incubator up and running and you have eggs, the incubation process begins. The incubation process generally takes from thirty five days to seventy days or more. One of the cool features of the Leopard Gecko is that you can almost decide which eggs you want to hatch out as males, and which eggs you want to hatch out as females. This is called Temperature Dependant Sex Determination. For the first twenty days or so of incubation, the temperature plays a role in determining what the sex of the babies will be. You will produce mostly males at temperatures of 88-90 degrees F, you'll get mostly females at temperatures of 79-83 degrees F, and you'll get a mix of males and females at 84-87 degrees F. If you incubate above 92 degrees F, it is said that you will most likely get “hot females” meaning a female Leopard Gecko that was hatched at a very high temperature. “Hot females” are normally very aggressive and are incapable of producing offspring. It is recommended to house them alone because of their aggression. The way I see it, is the warmer the temperature of incubation, the more territorial and aggressive the Leopard Gecko is since males are normally hatched at higher temperatures and are territorial. This seems to hold true for "hot females". I have no scientific data to back this up, but it would be interesting to pay closer attention to this. Anyway, after the first 20 or so days, the amount of pigment is determined. The higher the temp (in the 79-90 degrees F range) during the rest of incubation will give the offspring less pigment. The babies will have more pigment at lower temps. Also, the higher the temp, the quicker the babies will hatch.
So! If i hatch the egg for the first twenty days at 79-83 degrees¡ I will have a females!
Then I could rise the temperatures to 87 (79-90) degrees to determined the amount of pigment!
The best way to get intense color on a female is not through incubation but through genetics. Incubation color alteration is NOT genetic and in my opinion is false representation of the morph as the babies will not reflect the same enhanced color.
Yes! I understand you! and you are right! Generics IS the most important piece in having nice offspring! but im talking about the manipulation of melamine thru incubation.. In my opinion If i wanted to produce a Baldy or Patternless gecko I WILL try this type
of malipulation! and I dont think encubation will end up messing or changing the structure of genes of a particular gecko... that to Me doesent make sence.
I too heard of this. how you can manipulate the colors by rising the temp of incubation during the incubation of the egg. If i'm not mistaken, i read in the first 3-5 week period is to sex, and after that period you can manipulate the coloration. i never really found too much information on it, and i never proved it to be true. But if you do run into something that can help out this discussion. I would definitely like to know.
