Hello!

Bumble bees contain the spider gene, which has a 100% chance for a neurological defect called wobble. I am by no means an expert (heck, I am very new to the community, too!), but I've seen keepers greatly discouraging people from breeding anything containing the spider gene (such as bumblebee), since the wobble in bad cases can be incredibly stressful to the poor animals, and we are not 100% sure whether it doesn't cause them any pain...

In my own humble opinion it isn't okay to breed an animal for looks over health, knowing that it will have a neurological defect, and I wouldn't recommend breeding her at all... But, that isn't my decision to make here! So I would maybe recommend you to do research on the wobble and decide for yourself whether you still want to breed her?

(@The people here with more knowledge about genetics, is there a possible morph whose genes are dominant over the spider gene and would create non-spider offspring?)
