Roll? More like 'Skip'... :groinkick And you had him against the ropes, too.

I like to let him think he has won every once in a while. Otherwise he takes his balls and goes home...

Or if 2 normal parents have primarily chocolate or really light green colors, what are the odds that the babies will inherit those colors?

I think the reason why the genetics of normals are so hard to follow is probably because the genetics of the wild-type ball python pattern are so complex!

Even a single desirable trait of a normal pattern like blushing probably involves multiple genes interacting with each other and their environment during the course of development.

On the other hand, the traits of genetic morphs like spiders and albino involve only one gene and we can easily track their inheritance and plan to obtain them through simple Mendelian genetic crosses rather than make your best guess selective breeding which requires a trained, experienced eye.

Another difference is the traits of genetic morphs can be classified on an either or basis...your either spider or your not.....but a lot of the traits of "normals" full along a wide continuum--i.e. there is a tremendous amount of variation in the degree of blushing

It difficult to follow the inheritance of traits like that.....they are called polygenic traits (many, many genes and environmental factors involved) and require a different kind of genetics than the simple Mendelian Genetics of one, two, or three gene traits....they require analysis using what is called quantitative genetics.

Quantitative genetics basically uses statistical distributions (think bell curves) to make predictions...its a lot more complicated and requires very advanced training in statistics and genetics.

Dude, did they name "Mendelian crosses" after you? Thats so cool! :tongue2:

Jamie on the grounds of me being such a nice guy i will not ask how you know this :P .
