Breeding F2 to F1 generations

[mfick]

Question: Can I breed a snake to its parent? And for how many generations is this possible? Thanks...

Breeding an offspring back to a parent is a common practice to help isolate a gene, identify hets, create homozygous offspring, etc. You do want to limit how many generations are inbred as you can also start isolating "bad" genes as well as the desirable ones. I personally would make sure to start adding "fresh blood" into the F3 generation.

Thanks for asking this as I was actually wondering the same thing myself. Thanks for the info Susan

I have heard that mother to son can be bad, and father to daughter is ok? Or is that just opinion?

I've heard that somewhere myself, but really can't see any logical basis for it. Perhaps it related to certain inherited traits that are sex-linked, like sickle cell anemia, or maybe it's just an old male chauvinistic "rule" to allow a father to "doodle" his daughter but keep his son away from his wife/mother. (If you think about it, both theories had been relevant to the European monarchy and their families in past centuries.)

I am not aware of any sex-linked traits in corn snakes.
Without a sex-linked trait that you are trying to avoid, it should be the same.

I think you have a point about it being cultural, Susan.
