Ok, so Ive fallen in love with a snake, I know the breeder is very reliable and knows everything there is to know. The problem is the snake has a deffinate motley patterning over the top BUT has belly pattern, I know this is "unnormal". The thing that makes it even more unusual is that one of the parents is stripe the other is motley. Surely this makes it Snow het motley/stripe but then isnt that impossible and in that case it should have normal patterning not motley? Can someone explain to me how this works, I understand it shouldnt but it has.
And I really hope Im not talking a load of rubbish. Lol.
Thank youuuu. :)

to make it easier.......
a pair of chromasomes:
--------------
--------------
each - is a normal gene, and they come in pairs one top (inherited from one parent) and one bottom (inherited from the other parent). If each gene in a pair is the same, this is called homozygous (homo).
If a gene is mutated, we give it a different identifier, eg:
---a----------
--------------
a = amel. because only one gene is mutated, that is called heterozygous (het).
this would be homozygous amel:
---a----------
---a----------
Each morph has its own place in the pair of chromasomes, so het amel het anery would look like:
---a----b-----
--------------
or
---a----------
--------b-----
because motley and stripe are different mutations of the same gene they live at the same place on the chromasome, so homo motley is:
-m------------
-m------------
and homo stripe is:
-s------------
-s------------
if a corn is het motley and stripe (still called het because the pair of genes is different):
-m------------
-s------------
because both in the pair are mutated and there is no 'normal' gene to show the corn looks different, and because motley is dominant over stripe it's the motley gene that you see visually.

Hmm, ok. I think that makes sense. Thank you for tyhe explanation you are always very helpful!!

if one parent is motley and the other is stripe, then their babies will be het both and visually motley. This is because motley and stripe are different mutations of the same gene but the motley mutant is dominant over the stripe mutant. |

Sometimes when a snake is het for Motley the first few saddles can be joined like you would expect to see on a visual motley, however, the belly checkers are present. A motley will 100% show linked saddles and a clear belly. |

I have seen something similar to that on this site. It was a normal that showed partial motley patterning and had a section on his belly that didn't have checkers, ill see if i can find it. |

het motley , a piccy of the snake I saw, the belly doesnt show on this, but only half the belly has no checkers |

Ok so it could just be a het thats showing? So its a normal het motley but the motley kinda shows? :S Jeez Im a bit confuzzled! :P

No, because she isnt actually mine, but if I do get her (fingers crossed) I will put pictures up right away. Sorry. Ive thought about it so much and I dont know how it is possible. I dunno if this is just some completely unusual thing that should of never happened or if its just a mistake. I could really do with some genetics expert. Lmao.

Just out of curiousity... do you have a picture? |

Thats exactly it though its pretty much a fully grown snake, so what does it make it? I know motleys dont have belly checkers but normals dont have this kind of patterning, its confusing! :( Lol.
Thank you anyway for your reply.

Im by no means an expert, but if it has belly checkers then it isn't a motley, and yes it would be het for both.
Sometimes a snake can appear to have motley patterning, but it will likely stretch out as the snake grows. The saddle patterning isn't the only thing that makes a snake a motley. |
