Morph breeding question

I have bred normal corns and snows and some Amels. My question is, if I breed a stripe motley to a regular motley, then I should get regular motleys het stripe right? If not would it me poss het? What do yall think? I am trying to get this morph breeding down, I have some good projects for next year. I am thinking about breeding a snow and motley just for the heck of it to see what i get, I bet I will just get some snows and some motleys, maybe an anery or 2.
 
Is the one snake a stripe or a motley? I believe if both are motley yes you will get all motleys, if one is a stripe motley it doesn't necessarily mean it is het stripe so you will probably get all motley's again unles you have proven the other het stripe and then you ill have motley's het stripe I think. If you breed a snow which is an amel/anery it depends on what your motley is and if your snow is het motley.
 
yea al I know is that I have a male striped motley that I was gonna breed with a female motley, problem is, I have no idea what I have that are het for what. I know what some of mine are, but not all of them. guess I will have to breed to see. There is no telling what the motley is het for if anything. I don't think my snow is anything special, and the motley is probably normal.
 
I have previously thought about this before, so I checked it on the progency predictor to see what it says. The results say that you will get both Motleys and Striped Motleys! 50% and 50% to be be a little more precise. That's not saying that is EXACTLY what you will get, but that's what the predictor says.

From what I understand though, is that it is unclear if the striped trait and the motley trait are seperate genes. I believe that it's believed that they are on the same allele. Meaning it is the same gene that causes the two patterns. So if you breed them together, you could wind up with both?!

Now, I am not completely sure and if I am wrong, then I will be and stand corrected.

Sorry if I confused you.

Motley and Stripe are separate genes, but allelic (on the same loci).

First what you must consider is if the Motley-Stripe in question is a genetic Motley-Stripe (one allele of Motley and one allele of Stripe) or if it the selectively bred variation of Motley (two alleles of Motley - also known as Pin-Stripe or Ribbon).

So, starting at the very beginning if we're speaking of genetic Motley-Stripe...

Motley x Stripe =
het Motley & Stripe that phenotypically look like Motley or a combination of the two

Motley-Stripe x Stripe =
het Motley & Stripe that phenotypically look like Motley or a combination of the two and Stripes

Motley-Stripe x Motley =
het Motley & Stripe that phenotypically look like Motley or a combination of the two and Motleys (Motleys vs Motley-Stripes can not be identified 100% visually, so only breeding trials would be able to determine if they are in fact double heterozygous for Motley and Stripe)

A lot of confusing information, huh? ;)
 
yes I am lost. lol, Will probably have to just breed and see what comes out. I didn't raise the motley or motley stripe from eggs so I have no idea what they are. Bought the motley stripe from a breeder selling out. the regular motley was given to me along with 3 amels breeding size. I bred the amels this year so I will have some really cheap amels in a few months.
 
I got to think. I know someone on this site, wrote up a tutorial about snake genetics. I think it was Nanci or Susan, but I could be wrong. I am going to look and if I find it, I will post the link back on here.

I believe that a snake that is both motley and stripe (genotype) is technically het motley and stripe. This is because motley and stripe are on the same locus.

I'm assuming that you understand the genetic basics, like anery for example.
AA=normal... Aa=heterozygous (het) anery... aa=anery

Where AA x aa = 100% Aa

It gets a little more complicated at the motley locus because motley and stripe are 'connected' (for lack of a better word)...lets see if I can even explain it correctly

MM=normal
Mm=het motley
Ms=het stripe
mm=motley
ms=motley stripe (i.e. 1 motley allele, 1 stripe allele)
ss=stripe

Therefore a genotypic motley stripe x motley will look like
ms x mm

using the 'foil' method your result would be: mm, mm, sm, sm

Or in other words, 50% mm (motley), 50% ms (motley stripe)
 
lol, thank you Zoology that was helpful. I don't really understand how to know what is what. But I will learn more with studying. and research. But thanks.
