Not Good With Genetics - Help

I just took biology this year, so I understand the whole punnet square, heterozygous, homozygous, alleles, dominant, recessive, etc. But for some reason when it comes to snakes I completely blank out on it all. I guess I just need to brush up on it a little bit. Anyways, in a few months I'm getting a female BP, and probably in a few years start breeding. Considering the female I buy will be the one I will be breeding to my PASTEL in the future, I want to make sure I pick out a good morph. I know...

Pastel X Spider = bumblebee
Pastel X Bumblebee = Killer Bee
Pastel X Pastel = Supers

But what are some other cool things I could mix with my pastel that will give me something cool? I'd like to get me a morph that will produce me the best odds with my pastel. Please list what my pastel and the other morph will produce also. Thanks!

Search Pastel and look through all your options.

Best options would be to breed to any co-dom or dom morph, they all give the basic het square with the double dom being the combination of the two morphs.

Higher chances can only be achieved through breeding to a homozygous dom/codom.

Lower chances with better outcomes can be achieved by breeding to designer morphs consisting of 2 morphs, and in your case the bumblebee would be a good option.

Anything you breed to a pastel will look good! Pick a morph that you like the look of because you will be caring for this snake.
