will only get pastels,spiders & normals right?

It is possible for them to pass on the pastel and spider genes to the same offspring - so yes it is possible to get bumbles as well. :yessir:

Thats basically what I wanted to know is it possible to get a bee from this pairing?

1/4 bee, 1/4 pastel, 1/4 spider, 1/4 normal

Thats good to know :yessir:

Don't think I have seen any reference that jumps out in my memory of the odds hitting with any accuracy. Possible but don't know how likely, keep us updated if you do it.

Jayefbe is correct. Breeding a bumblebee to a normal is essentially the same as breeding a pastel to a spider to make bees. The same number of genes are involved, but in this case they all belong to one parent.
The bee parent has both the spider and pastel genes, each paired with a normal gene. The two mutations occur at different loci, and it must pass on one of each at each loci. That gives four possible combinations:
PS (bee)
Pn (pastel)
Sn (spider)
nn (normal)

These genes being co-dom and other parent is contributing only normal genes at all loci, so it's effect can be ignored. That leaves an equal chance to produce all four possible combinations in the offspring, each having a 25% chance.
