Hello,
I thought I had a pretty good handle on the genetics of leopard geckos but am now second guessing myself and feel confused.
Is there a good place to understand the basic genetics of leopard geckos?
Let me explain what I am understanding currently, please tell me if I have anything wrong and if there is anything else really important to understand.
There are dominant genes. There are only a few of them. (Does anyone know where I can find a complete list?) They all have a super form, or two copies of the gene, which means that if I breed the super to anything else then all. the offspring will always be visual. An example would be breeding a super mack snow to a normal, then all the babies will be mack snow.
There are recessive genes such as the albino strains, which means that you need two copies of the gene in order for them to become visual. If you breed them to something that does not contain that gene then they become a 100% HET and for the recessive to appear you need another that is HET to breed them together. If you breed two HETs and they do not become visual then the offspring will have a 66% chance of being HET. If you breed a HET to something that does not contain the HET then the offspring will not show the trait at all and will have a 50% chance of being HET. Any breeding after that will just have a possibility of being HET but that possibility is pretty slim. The only way to know for sure if they are HET is if they come from a visual recessive or if they produce a visual recessive when bred to another that is also HET. Is there a list of all recessive genes? I know you do not breed across the albino lines. Can anyone explain that and what happens if you do? I only ask to understand, I would never breed them together.
All other traits will only have a possibility to become visual but they have to have a copy of the gene to show up. This is where I get confused. How likely are they to show up if bred? Is there any way to increase the possibility? Are more than one copy needed to show up? Is there a term for these? Is there a complete list of these? Knowing that these are only possible. How did someone breed to get an almost completely black leopard gecko (black night for example)?
Please help me know if I am understanding correctly and if I am missing anything important. Thank you for your help.
