How to create a Killer Butter Bee?

[joe23]

i hate all those pre made calcs, this one can't get screwed up..... http://www.geneticswizard.com/

spider gene can only be het to our knowledge, so its impossible to have a 100% chance for spider babies. both parents having the spider gene would give you 25% normal, 50% spider, 25% homozygous spider(which to date does not exists and hasn't been proven and that why its thought to be lethal)

the pair you listed should yield 50% killer butter spiders and 50% killer butters

no- the calculator i used was right. u would get 25% butter super pastels and 75% butter killerqueens. i just backed it up with the wizard.

the first breeding yes- would give u 50/50, but the second breeding would give u 75/25


but thanks for the answer with the spider. i heard that to, that the hom form should be leathel, but i thought that was an unproven rumor.
