How to get a visual recessive x dominant ball python???? HELP

[Eric Alan]

I have been studying up on BP genetics here recently but im have a slight bit of trouble and was wondering if anyone could help me. Im learning the punnett square but im interested in finding out how its possible to get a visual recessive dominant animal like a banana pied or a pastel ghost and so on.

To visably pass along a dominant/incomplete dominant trait, only one parent needs to be carrying the gene. That's simple enough. In order to visibly pass along a recessive trait, both parents need to be carrying the gene (at minimum, be het for the trait).

So, in order to end up with a Banana Pied, for example, you need at least the following:

• Banana het Pied
• Normal het Pied

That way, the best case scenario is that all of these mutations are passed along to the offspring and you end up with a Banana Pied (1 in 8 chance with this particular pairing).

Clear as mud?
