So I've been thinking lately and Sakana is supposed to be a Hypo ph Lavender, Anery. Yet after doing some digging and searching I've found out her mother was NOT the Lavender het Anery that she was supposed to be. Her mother was in fact a Hypo with unknown hets. However, Sakana has a brother called Red who my uncle owns and Red is Amel... They are from the same clutch... So in theory Sakana's mum had to be het Amel and her father either also Het Amel or Amel himself... Right? Another theory... Sakana should be Het Amel which means in theory I should get some Amels from my Sakana x Cereus Pairing as Cereus is a Butter which is Amel Caramel! Right? Did I get that? |

Thank-You Eeji  That makes sense. |

copy pasta from another forum  .......
Inheritance:
Each morph has its own locus (place) on the chromosome, and there are two alleles present at each locus (one inherited from each parent). If these alleles are the same then that locus is homozygous, if they are different then it is heterozygous.
A morph is a mutation of an allele, but in the case of a recessive morph (recessive to normal) both alleles need to be the mutated version.
(note: this only applies to recessive morphs, which 99% of corn morphs are)
100% het
A recessive morph will be 100% het if one parent is a visual morph because that parent will have no normal allele to pass down - both will be the mutation so it is guaranteed that is what the babies will inherit.
66% possible het
If BOTH parents are het for the same morph, then any non-visual babies are referred to as 66% possible het. If we take a breeding of normal het amel X normal het amel as an example, the statistics predict that 1/4 will be amel and 3/4 will be normal. Out of the 3 normals, 2 are predicted to be het amel, but because you can't see the het we say they are ALL 66% possibly het - the 66% means that 2 out of 3 should be het.
50% possible het
If a baby is described as 50% poss het, this means that only one parent is het for a morph. Eg, normal X normal het anery: the stats say all the babies will be normal, but 1/2 will be het anery - this is where the 50% comes in. They will all be described as normal 50% poss het anery. |

As far as I'm aware Sakana is only Hypo ph Amel and nothing else but after all the messing about from her breeder she could be het anything lol. Cereus is a Butter and I don't think he has any hets but not sure. Got him from my uncle and my uncle had bred him but I don't know the parents hets. As far as I'm aware they were both butters but even he doesn't know if they had any hets as they were bought from shops. |

If a parent is homozygous for a trait eg "cc" for caramel then all the offspring will be het caramel. (Assuming the other snake does not have a copy of caramel.)
If the parent is het caramel "Cc" then there is a 50% chance that the offspring will be het (Assuming the other snake does not have a copy of caramel.)
If one parent is caramel "cc" and the other het caramel "Cc) then half the offspring will be caramel and the other half het caramel.
If both parents are het caramel (Cc) then 25% will be normal, 50% will be het and 25% caramel.
If you would like the workings then I can't do it on my phone. |

Trying to get my head round the genetics lol. If only 1 parent is carrying the gene for say Caramel(Butter = Amel x Caramel) then would the hatchings not be only 50% chance of being het for it? Or am I on the wrong track? Same thoughts for Hypo too. |

any amels would be 100% het hypo (from Sakana) and 100% het caramel (from the butter), as would any normals which would also be 100% het amel (from the butter) |

if you breed with a butter the none visual amel hatchlings will be 100% het, this will be coming from the butter parent.
So if she is het, have I got any guarantee of getting Amel hatchlings that are PH Caramel and Hypo? |

The whole thing leaves my head spinning;I've got a completely random (not inherited)genetic disorder.
I think half the reason we like our George so much is that he was a random one off-all his clutch mates were normal/normal motley and his parents were normal coloured.

Ive got a couple of those disorders too pmsl im a medical mishap me i swear! i couldnt ever grasp the genetics stuff when drs tried explaining it too me over the years but when i discovered that corn genes were recessive too that was it i suddenly had to crack it and learn how it all worked lol and its obviously applicable to my condition well the principles are anyway haha |

<biology teacher mode>
Key: A capital letter means that the allele (a different form of a gene) is dominant. In all these morphs the normal allele is dominant. For the morph to be seen in the offspring it needs to have two copies of the recessive allele (homozygous).
For the gene hypo H = normal allele, h = hypo allele.
For the gene Amel A = normal allele, a = amel allele.
For the gene Caramel C = normal allele, c = caramel allele.
Ok, so starting with the easier cross. Assume that Sakana has no hets
Hypo crossed with butter
hhCCAA x HHccaa
all offspring will be HhCcAa (normal het hypo, caramel, amel)
If Sakana is hypo het Amel
hhCCAa x HHccaa
50% offspring HhCcAa (normal het hypo, caramel, amel)
50% offspring HhCcaa (amel het hypo, caramel)
</biology teacher mode>
I hope I haven't made any mistakes; that would be embarrassing |

Well I was thinking like, if she's het for Amel and Cereus being a Butter(Amel x Caramel) would it be....
3/4 Normal het Caramel, Hypo & Amel.
1/4 Amel het Caramel & Hypo.
or something different? And if Sakana is het Amel will the hatchlings only be poss het Amel? Am I getting ANY of this right? XD |

Well Butters are Caramel X Amel So amels are a possibility |

I've no idea what dad was. Mum was sent off for mating and Sakana and Red were both produced from the same mating and clutch. I am hoping missus angry at everything and doesn't want to eat is gravid so that I can attempt to prove out whether she's het Amel but not sure yet.

Haha, I wish lol.
If both parents were "Het" Amel then Sakana would be 66 percent poss het amel the fact that Red was Amel means both parents carried Amel genes in one form or another but breeding Sakana to your Butter will definately prove her out one way or another
If she is Het for Amel... What will I get from them? Here's the full extension of what I know of the pair now.
Sakana - Hypo PH Amel
Cereus - Butter Unknown(if any) hets. |

haha :) i think it's truly fascinating, also the variations of the same gene as well |
