Understanding Western Hognose Morph Naming Conventions
1. Bloodline / Lineage Name (Polygenic Traits)
- Position: Typically placed at the very beginning or separated by a comma.
- Significance: Represents that the individual originates from a specific breeder's lineage and is a particular expression achieved through years of selective breeding. This is a polygenic trait.
- Explanation: "Lemon Ghost" is not the name of a single gene. Instead, it refers to animals from that specific bloodline whose unique combination of multiple loci results in an exceptionally bright yellow, clean appearance. An animal can only be called a Lemon Ghost if it is verified to originate from the breeder who developed that bloodline; the name cannot be applied just because an animal looks similar.
2. Visual Morphs
- Position: Placed immediately after the bloodline name.
- Significance: These are the phenotypic traits that you can see directly with the naked eye.
- Explanation:
- Dominant / Incomplete Dominant Genes: Such as "Arctic" or "Conda."
- Homozygous Recessive Genes: Such as "Albino." Recessive genes must be paired up (homozygous) to show visually. If only a single copy is carried, it will be labeled as "het."
3. het (Heterozygous)
- Position: Placed after the visual morphs.
- Significance: This is a genetic state that is invisible to the naked eye. Although the animal looks identical to a wild-type individual, it carries a single copy of that recessive gene at its locus.
- Function: When this snake is paired with another individual carrying the same gene, there is a statistical chance that the offspring will produce the visual expression of that gene (such as Albino or Sable).
4. ph / % (Possible het)
- Position: Usually placed at the very end of the name.
- Significance: This is a probability-based prediction. In certain breeding pairings, it is impossible to determine visually whether an offspring carries a gene or not. We denote these values based on genetic probability.
- Explanation:
- 66% ph: Produced by pairing two heterozygous parents (het × het). Among the non-visual offspring, there is a 2/3 probability of carrying the gene.
- 50% ph: Produced by pairing one heterozygous parent (het) with a non-carrier (Normal). The offspring have a 1/2 probability of carrying the gene.
- Validation: In practice, this is a game of probability. The genetic status can only be proven through test-pairing or genetic testing.
Example Analysis:
Let's analyze this specific snake: "Colorblast Line, Swiss Chocolate Conda 66% ph Albino"
- Colorblast Line: This indicates that the individual carries the Colorblast lineage from JMG Reptile. It guarantees selective breeding value, presenting with enhanced red blushing and richer coloration.
- Swiss Chocolate: This is the visual expression of a recessive gene. It means the phenotype displays the characteristic melanistic tones and dark gold appearance unique to the Swiss Chocolate morph.
- Conda: This is the visual expression of an incomplete dominant gene. This snake possesses the signature large, reduced blotch pattern and the clean belly characteristic of a Conda.
- 66% ph Albino: The snake does not visually show Albino, but there is a 66% chance that it carries one copy of the Albino gene. If you are lucky enough to hit that 66%, pairing it with an Albino in the future will produce visual Albino offspring.
