NORMAL X Bumble Bee

Hi,

I want to ask that why NORMAL X Bumble Bee the result is
25% normal, 25% pastel, 25% spider and 25% Bumble Bee?
not 50% spider and 50% bumble bee???

Thx!

It would be 50/50 if you bred a SPIDER to a Bee. Normals do not carry any of the genes that make a Bee, but Bees have two sets of genes that make them what they are. The normal cuts down on the chances of those genes getting expressed, hence the 25%s.

At least I think that's right... it's nearly Midnight and the science part of my brain is already asleep. :D

you wouldnt actually get bees would you breeding to a normal?

shouldnt it be normals, spiders, and pastels?

but like its been said its 4am and im not to crisp

that's what i thought too but somebody hatched out a bee with a bee x normal breeding in another forum.

Original poster is right

1/4 Bees
1/4 Spiders
1/4 Pastels
1/4 Normals


This holds true with any double codom except supers with all the babies being the original morph...for example super pastel to normal would be all pastels

The reason is this: there aren't just two alleles controling the physical appearance of the animal.

Let's say each parent can now contribute two genes: Normal will always contribute normal, but Bumblebee will contribute any one of these:

SpiderNormal PastelNormal NormalNormal SpiderPastel
to the genes of the normal, and as such each of the resulting children will get "NormalNormal" from mom, and any of the four others from dad. But because dad has one normal allele to match each pastel or spider allele, he still contributes two, just that the spider, or pastel, or 'bumblebee' ones show up.


So, the resulting children:


------- Spidernormal ---- Pastelnormal ---- NN ---- SpiderPastel

NN ------SpNNN-----------PNNN-------------NNNN----------SpPNN

NN ------SpNNN-----------PNNN-------------NNNN----------SpPNN

NN ------SpNNN-----------PNNN-------------NNNN----------SpPNN

NN ------SpNNN-----------PNNN-------------NNNN----------SpPNN



Does that make any sense?

The main point to remember is that the spider and pastel mutations are at two different gene locations. There is not just one normal gene of importance here, there is a normal version of the gene at the spider location and there is also a normal version of the gene at the pastel location.

The bumblebee parent gives one copy of each gene. For the spider gene there is a 50/50 chance it will give the spider mutant version rather than the normal for spider version. There is a completely separate roll of the dice for the pastel gene with another 50/50 chance of giving either the pastel mutant version or the normal for pastel version. The combined effect gives you the 25% split of chances:

normal for pastel + normal for spider = normal baby
pastel mutant + normal for spider = pastel baby
normal for pastel + spider mutant = spider baby
pastel mutant + spider mutant = bumblebee baby

Wow, i'm new here and i think that the way you broke the diagram down is a great asset to newer breeders like myself.

So this would also apply to the pewter i'm purchasing then.
So now I do not need to focus on putting a cinny with a pastel. Am I correct?

Correct, pewter has both cinnamon and regular pastel and they are separate genes so pewter X normal produces eggs with the following possible genetics:

25% chance normal
25% chance pastel
25% chance cinnamon
25% chance pewter

Now when you start getting into different mutations of the same gene like say a leucistic produced by lesser bred to mojave the rules change. This is because the two mutations combined are different mutations of the same gene. The result is that the luecistic gives each baby one or the other but can't give both. So one of these cross line lecistics (and I believe this would include platy and possibly crystal) bred to a normal would produce eggs with the following possible genetics:

50% chance leucistic side grandfather (lesser in our example)
50% chance leucistic side grandmother (mojave in our example)
