Pattern phase Grey-banded Kingsnake
How wide the bands are and how much orange or red they carry. Blair's phase animals are broadly banded and strongly red; alterna phase animals are narrower and greyer. Both come from the same species in different parts of its range.
How it is produced
- Where it comes from
- This is not a single gene. It is produced by choosing which animals to breed, over generations.
- What that means for breeding
- No offspring percentage can be given for it. Breeders judge it by looking at the parents.
Offspring odds
No numbers for this one.
Pattern phase is produced by selective breeding over generations, not by a single gene, so no offspring percentage can be given for it. Breeders judge it by looking at the parents.
Worth knowing. The phases are regional pattern types rather than genes, so a pairing between them does not give a ratio of either — and animals intermediate between the two are ordinary rather than a failure.
What this rests on
Established by breeders through repeated crosses and recorded in community documentation, not by published genetics. That is how almost all morph inheritance is known — and it is worth saying rather than presenting it as laboratory fact.
