3rd litter born today- 25 big healthy babies

[Jeff B]

The 3rd litter of the season for me was born today. Ended up with 25 perfect big babies and ZERO slugs or stillbornes. After having a bad year last year this season is going pretty darn good. Must have done something right this season. The dame was a T. radix (plains) het axanthic (one of her parents was axanthic so she had a 50% possibility of being het axanthic or het anerythristic). The sire was an axanthic visual (so being co-allelic he carries one copy axanthic and one copy anerythristic).This means the sire would have to donate either a copy of axanthic gene OR a copy of anerythristic gene. About half the babies born are axanthic and the other half are normal phenotype. Thus proving out that the female is in fact het axanthic (or she carries one copy of the axanthic gene). This also means that all the normal looking babies are 100% het anerythristic. If the dame would have been het anerythristic half the babies would have been anerythristic and the other half would have been normals het axanthic. Hope I didn't confuse anyone.

Awesome! You were do for a good season.

You lost me but it doesn't matter. Awesome radix scrubs.

Thanks Ed. You know I took a lot of flack last year and in fact I took a lot of flack right up to last week. Last year was a bad year with a lot of stills for whatever reason for me and then to have to listen to all the crap on top of it, was just adding insult to injury. Hope these litters continue. Can't wait to see how the rest of the week pans out at this rate. My florida albino and het albino that I got from you (was it 2 or 3 years ago?) are looking plump. They were both bred to my 4 het pieds rotating for a month.

Sorry Steve, I was afraid that might be confusing, co-allelic is a somewhat complicated situation and maybe I didn't explain it as well as I hoped. Read it again tomorrow and hopefully it soaks in while you sleep tonight and will make sense tomorrow Maybe think of it this way axanthic and anerythristic exist at the same location and only two copies can exist at one location.
Lets label axanthic allele=x and label anerythristic allele=n X and N represent their respective wild type alleles
xn=axanthic phenotype (looks black and blue)
nn=anerythristic phenotype (looks black and gray)
xx=normal or axanthic or lethal, not completely sure yet
Xx=normal phenotype (looks normal) but het axathic
Nn=normal phenotype (looks normal) but het anerythristic
Hope this helps

I'm with you except for "xx=normal or axanthic or lethal, not completely sure yet". You lose me there.

It does, Thanks

If I understand Jeff correctly, he has yet to determine what the phenotype of an individual that has a genotype of "xx" would be; whether normal or axanthic, or if it is a lethal mutation all together that terminates the developement of fetus.

P.S. Awesome litter there Jeff! It is hard to beat a good looking axanthic radix.

[Jeff B]

That is correct Thomas. Thanks
The axanthics don't look like much as babies, just a dull darker version of normal, but if you look at them under a magnifying glass they have an irredescence to them and they have blue bellies. As they mature into adults they turn a nice blue, slate gray and black, one of my favorites for sure.
I'm really hoping to prove out the Chicago green axanthic in the next couple weeks, but that may end up to be a 3 year wild goose chase. The wild caught green axanthic male is really nice.

Nice explanation.
So anerythristic and axanthic are both recessive, and when both genes are present it is the axanthic trait that is expressed.
