Bumblebee het axanthic x Axanthic spider?

[SuperD]

Hi is it at all possible to breed Bumblebee het axanthic with an Axanthic spider?
Or is it like breeding two spiders together and getting slugs?

[MrLang]

It's fine - when you breed spiders together you don't get all slugs guaranteed either - you just get spiders and normals and no 'super spiders'


I can't say for sure whether or not slugs are more or less likely to be produced by spider x spider, but I have never read anything that says this.

Doesn't spider to normal give you approx. 50% spiders. Would spider to spider give you more like 75% since it's a heterozygous allele?

Nope. It would be either 50/50... or if there is a "Super Spider" it would be 25% Super, 50% Spider, 25% Normals.

Yes, you have 75% each egg will be a spider, from spider x spider breeding. But since you are breeding bumble bee het ax to spider ax, you can get ax bee,spider,pastels, regular ax, and get bees, spiders pastel and normals all het ax

[MorphMaster]

No I'm positive because even pastel to pastel guarantees 75% of the babies carry the pastel gene, but because it's codominant you get 25% with the homozygous allele.

Morph- you are correct and incorrect lol. Your are incorrect because there is no guarantee that 75% of the babies will carry the pastel gene. You do however have a 75% chance of getting a pastel per egg. You could get all pastel(or spider) or get terrible odds an get all normals..

That last part is incorrect. It's a bumblebee HET axanthic- not an axanthic bumblebee.

Yes, you have 75% each egg will be a spider, from spider x spider breeding.

For every paired sperm and egg, you have a 50% chance that the resulting genotype is a heterozygote with regards to the spider trait. You have a 25% chance that it does not carry the trait at all, and a 25% chance that it is a homozygote.

However, due to the ongoing uncertainty regarding what the heck is going on with the lack of a "super spider", it's probably safe to say that we can throw homozygotes out the window. I don't know any statistics on the matter, but if any sperm/egg pairing with a homozygote genotype fails somehow, then it's safe to say that the percentage results of suriving offspring are as such:

1/3 are normal
2/3 are spiders.

Either way you look at it, claiming that spider x spider will result in 75% "spiders" isn't correct, unless you can show us that homozygote spiders don't have reduced survivability and are the same phenotype as heterozygote spiders. Still, even if that were the case, I'm a fan of full disclosure when answering inquiries to breeding results, and the best answer to "what are the odds with a spider x spider" breeding (assuming that homozygote spiders have full survivability and look like regular spiders) is to say that 25% of the offspring are normal, 50% are spiders, and 25% are super spiders.

That last part is incorrect. It's a bumblebee HET axanthic- not an axanthic bumblebee.

I know it's a bumble be het ax, so bumble bee het ax bred to a ax spider will Produce normal babies that are 100% het ax. So how is that incorrect?
