Keltic Boa Constrictors
Keltic is a boa constrictor gene closely tied to Colombian Motley, and that link is the most important thing for a breeder to know. A snake with both genes is called Smoke, which is a fatal combination. You must know what is in your Keltic's lines before you pair it.
About the Keltic gene
The Keltic boa constrictor gene is closely tied to Colombian Motley. You must understand this link before breeding from one, as having both genes in a single snake does not make a healthy animal.
Genetics
There are two forms in the family, Super Keltic and Keltic. Keltic is a trait related to Colombian Motley. A snake that carries both Keltic and Motley is called a Smoke by the hobby. Smoke is the name for that two-gene animal and is not a gene of its own.
Known issues
Smoke, a snake carrying both Keltic and Colombian Motley, is a fatal combination. That is why a Keltic's lines matter before it goes into a pairing with a Colombian Motley.
