Hi there,
Genetics are considered theory until proven. The Pastel example you gave is a good place to start. The first Pastel that was found was wild caught. This snake "randomly" appeared, like other wild caught "morphs". Its parents are unknown, so there is no way to find out what they looked like, but we know by looking at the snake it is different. Since the gene was proven to be CO Dom, when bred to a normal, the babies theoretically should be as follows;
1. Half the babies will be Pastel, they will look like and carry the gene
2. The other half will be normal, non gene carrying.
Since genetics are a theory until proven, we can not say that out of 10 eggs, 5 will be Pastel, and 5 will be normal. I have seen this ratio shot to death when out of 8 eggs that hatched only 3 where Pastel and rest where normal. Co Dom traits either have or don't. Recessive genes are the ones that are hidden. Pieds are recessive, and if you bred a Pied to a normal, all your babies would be 100% Hetero for the Pied gene. Non would be hatched as a Pied. You would need a Pied and a Het, 2 Hets, or 2 Pieds to make them.
