I hear ya Big T, now some of the percentage break-downs on multi-morph breedings can be a bit more complex to grasp at first, but as long as one keeps in mind that only paired "LIKE" genes from BOTH parents will make any given morph offspring, then it is much easier to understand. And any odd gene that only ONE parent has, will mean this cannot be expressed in any of the offspring. It's really all about matching genes.



With het genes in colubrids, if each parent is say het for amel, but looks normal visually, when these two snakes are bred together, you will have a theoretical 25% of the clutch that is homozygous(visually displaying) for the trait, 50% that is het, and 25% that is normal. But the clincher is you will not know which ones are hets and which one's are normal, so ALL of these would be known as 66% het, or 2/3 chance of being het. These would need to be proven-out just like we talked about with the hybino and pearl scenarios.



* Homozygous to het breeding = 50% homozygous, 50% hets



* Homozygous x Homozygous breeding - 100% homozygous



here is a link below to Terry Dunham's website that helps explain some basic genetics too. There are also genetic calculator programs that break down the precise percentages as well.



There are countless sites that also explain how recessive genes work and are inherited. I used to think this was all like "rocket science" too, but once I grasped the basic fundamentals, it all was much easier for me to understand it all..LOL!



Anyway, hope this helped just a bit, and didn't just confuse even more..LOL!
