:eek:
I have a genetics problem. I have an anery a, I'm figuring he is rrBbssYyww, r-red, b-black, s-pattern, y-yellow, w-(snow)albinosim. If he is bred to a anery a het snow, Would her's have four digit letters with one extera for het, or what? rrrrBBbbssssWwww? Is that correct or is there a way easier way to do it? I can explain it in words, but not in letters! Help! I wanted to find out the percentage of their babies to be what? Please help me understand..... ha ha ha, I'm so clueless. Thganx-from an amateur genetics geek.
 
What makes you think that this Anery is Yy, ss, or ww? If it is just a standard Anery (without hets) then it is only reduced in red pigmentation.
 
The "pattern" is controlled by a whole lot of genes... Motley and Bloodred and zigzag are only a few of them that we've located. No "yellow gene" has been located yet, so you won't be able to predict whether or not your offspring will develop yellows.

Anery and amel are single mutations. In the system you're using, each is represented by a letter pair.

Anery can use the letter "e," and amel can use "a." Don't worry about the rest of the genes, as they aren't part of what's being predicted. What I mean is this: if a cornsnake has 50,000 genes, you could try to represent all of them with letters, but this would be like saying 5 + 1 = 5 + 1 + 0 + 0 + 0 + 0 + 0 + 0 + 0... ;)

Snow is what you get when both anery and amel are homozygous (aaee) so your anery is AAee and your anery het snow (Anery het amel) is Aaee.

To pair them up, pick only one of each letter from each parent:
Aaee can produce eggs Ae and ae
AAee can only produce sperm which are Ae

Pairing up the one type of sperm with either type of egg, you get two outcomes:

AAee (Anery, not het amel)
Aaee (Anery, het amel... also called "Anery het snow")

Those are what can come out of any given egg. :)
 
How would you represent a hypo trait? Sorry I'm so nosey and kinda dumb, but it's all so fascinating and I love learning more and more about this stuff.....Thanks for replying and being patient:)
 
Hypo would be another letter. H works well. :)

Same goes for any of the recognized traits, just pick a letter and use it for your calculations. Only if you're exchanging genotypes with someone else do you need to worry about how you represent it. :)
 
Like Serp says, try to keep it as simple as possible and in a way that you can understand easily. If your just dealing with anery A and snow, 2 letters is enough. I'm a little crazy (OK...alot crazy!)and bred my caramel motley to my ghost so I'm dealing with offspring that have lots of letters (RrBBCcHhMm). But I picked up on Mendelian genetics and the Punnett Square thing way back in high school biology. And I still have questions! The newest one concerns anery B. I just got my very first charcoal and she's the only one in my collection with that gene. Luckily, I have several years to figure out how it works with anery A and snows. Or to save up enough money to buy another charcoal or a blizzard and then I don't have to worry as much about how many generations it will take me to produce another charcoal. I could always go to Serp's site and try to figure it out there, but that may be considered cheating!

Anyway, once you get the hang of the genotype thing, you'll be figuring out all kinds of possibilities and having alot of fun!
 
Thanks for the info guys. One more quick question. Sorry, but I read somewhere that bloodreds have three link genes, two are recessive and the other, oh I can't recall what it said, but it really threw me off. Anyways, if you can understand that... but I really apreciate you explaining this=)
 
I understand linkage. That just means that the locations of two independent genes are fairly close together on the same chromosome.

I hadn't heard that any linkages had been found in any snake species.

Can you find and repeat the information here? Somebody ought to be able to interpret it.
