What's the best resource/article for figuring this out myself?
I've found some, but they aren't very complete and don't allow mixing and matching.

What will the outcome be for these mixes:

bumbleebee x normal
bumblebee x albino
bumblebee x pastel

also

killerbee x pastel

How does the double reccessive work? Like how would one go about getting a pied snake with a killerbee head?

Let me try to take a shot at this one..

bumbleebee x normal
25% normal
25% spider
25% pastel
25% bumblebee

bumblebee x albino
same as listed above,but will be het albino

bumblebee x pastel
25% normal
25% super pastel
25% spider
25% killerbee

killerbee x pastel
50% super pastel
25% killerbee
25% bumblebee

How does the double reccessive work? Like how would one go about getting a pied snake with a killerbee head?

breed a spider het pied and a super pastel het for pied and cross your fingers

Bumble bee X Pastel would not produce any normals .

"Bumble bee X Pastel would not produce any normals"

Why not?
If pastel x pastel produce normals, why wouldn't spider pastel x pastel?

Just looking for your logic.

Correct, bumblebee X pastel produces eggs with a 12.5% chance of being normals. Basically you are talking het X het on the pastel side so 25% chance normal for pastel. On the spider side it's het X normal so 50% chance normal for spider. The combined chance of being normal for both spider and pastel is then 12.5%.

A few corrections to earlier posts:

bumblebee x pastel (this is basically het X het 25/50/25 split on the pastel side with het X normal 50% spider laid on top of it)
12.5% normal
12.5% spider
25% pastel
25% bumblebee
12.5% super pastel
12.5% killerbee

killerbee x pastel (this is homozygous X het on the pastel side so 50/50 split pastel and super pastel with 50% spider laid on top)
25% super pastel
25% killerbee
25% bumblebee
25% pastel

“How does the double reccessive work? Like how would one go about getting a pied snake with a killerbee head? “

A pied killer bee is homozygous for both pied and pastel and heterozygous for spider. So for the homozygous genotypes you would need at minimum pastel and het pied on both sides but spider only on one. So one way would be a bumblebee het pied X pastel het pied.

All of these cases are made much easier by breaking everything down to it’s genotype (heterozygous or homozygous) which requires understanding that pastels and spiders are heterozygous for their respective mutations.
