haha ya you are, lemmie get another punnit square going on for that.

*smacks face with palm*
i thought he said 100% pied x 100% ALBINO

haha, i need better glasses

Purrrfect9 -

Thanks for putting up with me. When I want to learn something, I'm sooo full of questions. Genetics has always been an interest of mine, and during Bio class last year, I had all 3 of my lab partners asking me to tutor them in the genetics portion of class. Too bad I don't retain information. lol. I have to study something over and over and over to get it. Thats kinda what I'm doing in this thread.

Ok, with this, from what I understand...

the Sp means it has the Spider pattern and carries the potential for pastel, correct? Because the S is capital it means its dominant and therefore shows. Little p means recessive and that it is only potential unless coupled with another little p. Correct?

Little s means it has the potential for normal, but will not show unless coupled with another little s. Big S means it shows the spider pattern. So a Ss is a 'het' spider. Because spider is dominant, it shows the spider markings.

Pp means it shows the pastel coloration, and has the potential for normal, right? So two little p's brings normal coloration, and two P's give pastel. Pastel is co-dom thought right? Does that mean it shows up even in het form? and homozygous dominant will give you a super pastel, right? (I'm a little confused on this one)

But lets say you have a SsPP, would that be a Killer Bee, or just a Bumblebee? Or neither?

(^ I wasn't looking at the punnet when I asked about the SsPP, but now that I look, I think I'm right.)

Jay-
It's no problem at all. When I can explain this stuff to other people it helps keep it fresh in my head and also helps me to understand/learn it better ^_^

Here's the chart for Spider X Albino crossing. This is a very good example as to why you should know if your spider is a homozygous or heterozygous spider.

If it's a heterozygous spider, you would get 1/2 spider 100% het for albinos and 1/2 normal 100% het for albinos. If it's a homozygous you would get all spider 100% het for albinos

Oh I get it now. Because the albino is lending only one recessive gene, the normal from the spider dominates it, causing a normal. But if you have A spider that is homozygous there is no normal trait to give and all resulting offspring are therefore spiders.

Am I getting it now?

You have the S part correct. The P's and p's for pastel work in the same manner as the spider genetics do. p=normal coloration in that certain chromosome 'slot'. s= normal patter for that chromosome 'slot'. But, if you get Pp= pastel, and PP= super pastel.

This is where Co-Doms can get confusing. two big P's will give you a super pastel. a Homozygous dominant trait for the pastel will give you the super form. This holds true for Mojave's and Lessers ( for the BEL) as well. But if you have a Pp, you will just have a regular pastel ( like the lemon, or graziani or w/e)

Yes you would have the Killer Bee with those genetics. Since it only takes 1 dominant allele for the spider trait to show up, you can have Ss, but in order to get the "Killer Bee' part of the Bumble bee, you have to have both dominant alleles for the pastel to show up ( PP), essentially it being the superpastel with the spider pattern.

:rockon: exactly!!! See, it just takes a little bit of practice to get going ^_^ And just think, we're not getting into the double recessive morphs like the double het pied and het albino stuff yet ^_^

This genetics wizard rocks the socks....

Choose the number of abnormal traits in step one.

Name the traits you are dealing with and determine if they are recessive, dominant, or co-dominant. (recessive is the default so check nothing if you're dealing with a recessive gene), then choose if the parent is a heterozygous carrier or a homozygous carrier (remember there are still heterozygous carries of co-dominant genes - a pastel is a heterozygous carrier of the pastel gene, but since its co dominant, the gene shows).

Woot! I'm getting this!

So in order to get a Killer Bee you would cross what two animals? Obviously, each would have to be either het for Pastel (which I guess would result in supers, normals, and dominant hets, right?) or homozygous for Pastel (which would be the super Pastel), and they would have to be Het for Spider or homozygous for spider. Am I correct?
