Super Pastel x Spider....?

What would this yield in a typical clutch? I guess the main question is Super form of Co dom X Co Dom....Thanks!

I believe you'd get

50% pastels
50% bumblebees

A Super Pastel X Spiders produces a Killer Bee. And I think the numbers are: 25% Killer Bee, 25% Spider, 25% Pastel and 25% Normal on average.

A Killer Bee is a Super Pastel Spider...

You can only produce a Super Pastel if both parents are carrying the Pastel gene.

Also You don't get any Normals when breeding a Super Pastel.

What Jon said!

Just remember that each parent has two copies of each gene but only passes one copy to each offspring. So even though both the super pastel's copies of the gene at the pastel locus are the pastel mutation it can only give one pastel mutant copy to each baby. The spider parent has two normal copies at the pastel locus so can only give one normal for pastel copy to each baby. So every baby is heterozygous for pastel (i.e. a Pastel) with one pastel copy from the super pastel parent and one normal for pastel copy from the spider parent.

The spider mutation is at a completely different locus so a separate problem. The super pastel has two normal for spider copies so each baby gets one normal for spider from the super pastel. The spider is heterozygous for the spider mutation with one normal for spider copy and one spider mutant copy so each baby has a 50/50 chance as to which type of the spider gene (mutant or normal) it gets from the spider parent.

So overlaying the two results (all pastel and 50% spider) you get the 50% chance just pastel and 50% chance both pastel and spider (bumblebee).
