Hehehehehe!

actually a het to het breeding will only yield 25% albino the rest would be 66% hets because you would not know which ones are hets.Albino to het would yield 50% albino The rest would be 100% het.A het to a normal would yield all 50% hets

I think you're right, although I dont feel like looking it up.

And keep in mind, Steph, this is in theory. If we say het albino x albino = 50% albinos, you should end up with 4 out of 8 babies being albino, but in reality, it might be a couple more or less- but on the average, it will be near the numbers.
Although when 100 % or 0 %, its pretty much a firm rule.

Wow, it's so nice to get so much input from so many smart people!!! I'm a stay at home mom, and it's nice to get some "brain food"- it's not exactly challenging singing "the wheels on the bus" and watching Wow Wow Wubzy with my daughter!

I do remember genetics from HS/College, and doing the Punnet squares etc. Now, to take this further, are the color morphs simple or I remember something about "multiple alleles". I do not, however, remember if that is multiple sites on the same gene, or multiple genes, or something else entirely. (But I know it will all come back to me when I read your posts!) Are some color morphs simple while some are complex?

What prompted this was when I looked up "piebald" I got a lot of coat color genetics info on horses. So for example, the gene for a certain coat is recessive, but because coat color/markings/patterns are governed by multiple things, one homo-recessive "over" (not quite sure what they meant by that) another recessive gives another coat color, but when "over" another type of recessive it gives a third color, etc. etc. etc...

And about the "how many of them will be Het, how many will be Albino", my understanding was that it wasn't that 50% of a litter, clutch, brood etc. should be that, it's that each genetic combination has a certain percentage chance that it will be of a certain genotype. From horses, I know that even though a mare or stallion is hetero for a gene, he/she may never "throw" that gene. So a beautiful paint horse, with flashy color, may never, ever in his/her life send along the gene for that, and have plain brown babies EVERY time, despite being bred to a homo-recessive mate. So it is possible (I understand not probable, though) that a Het mated to an albino will have no albino, only het babies, and two hets "could" have only Homo-Dominant babies.

I know I'm probably getting way ahead of myself for practical applications of this knowledge. Heck, I'm just looking to get my first Thamnophis, not anywhere close to breeding where I'd *need* it. But like I said, I really enjoy thinking, and you all give great brain food!!!! AH, I feel the cerebral fluid warming now!!!!!!

Hope you're enjoying this as much as I am,

Gods, Stephi, you've got me wetting my pants here as I laugh!!!

Too funny! But can understand from where you come - not that I have or ever have had widdo wee scaless ones! Just can understand the need for brain candy and like minds.

Too cute! You crack me up!

GO, GIRLFIEND!!!!!!!!!!! Better to have the knowledge before you need it, than to be in dire straights (Would that be a good name for a rock group???) and scrambling for the info.

I am very much enjoying having you here! Not laughing AT you; laughing with you! Nice to have you!

Wow, Stephi, sounds like I should be asking you the questions.
I think your explanation of the percentages of hets vs. homo's is more accurate than mine. You pretty much got it as far as I would know from my basic understanding of this stuff.
As far as I know, it seems like the majority of snake morphs are simple recessive, but I could be wrong.

[Loren]

So, here is a link for anyone interested- look to the left column for genetics 101-601- 6 lessons on snake genetics.
The Learning Center - Genetics 101

There's actually several other pages on care and breeding that might be good reading too.

Sigh... genetics make my head implode.

[Loren]

yeah Lori?, try reading the "genetics 601" page first, whoa!

Can I drool over this picture!!! I would love to have one of these snakes!!! It;s ok my ball is gorgeous!! he he
