>What would the possible outcome be with breeding a bumblebee to a pastel?

As I understand it, a bumblebee's genotype is heterozygous spider and heterozygous pastel. And the pastel's genotype would be heterozygous pastel and normal at the spider locus.

pastel (heterozygous) x pastel (heterozygous) -->
1/4 homozygous pastel = super pastel
2/4 heterozygous pastel = pastel
1/4 normal

spider (heterozygous) x normal -->
1/2 spider (heterozygous) = spider
1/2 normal

Putting the two loci together, I get
1/8 super pastel, spider = killer bee
1/8 super pastel, normal = super pastel
2/8 pastel, spider = bumblebee
2/8 pastel, normal = pastel
1/8 normal, spider = spider
1/8 normal, normal = normal
