Hi Zero 
As our very own Dr Wyman puts it… “Genetics is genetics is genetics”.
Whether it’s a cat or a lizard, genetics has to follow its own set of rules. So yes, boas and BPs follow the same rules.
Using the “genes and traits” list on the marketplace you can work out which ones are recessive (needs two copies) and which ones are dominant (needs only one copy)…
Yellow, orange and pink represent recessive.
Blue and purple represent dominant.
Gray represents other (wild type, paradox, line bred traits).
Now you know that, you can use the morph calculator to see what results from any two pairings…
I hope this helps, if you have any more questions, no matter how simple or complex, feel free to ask them.
