How important is F1 or F2 breeding in snakes?

I am looking at various species of snake, and some lines are noted "F1" or "F2". I am assuming this is some indicator of genetic purebred lines, is this an accurate assumption? What then is F2? Second generation from wild-caught specimen, or has an alternative bloodline been mixed in?|||To do this you'd first have to know the P generation is the parents. One has a desirable trait that the breeder is trying to reproduce.





Think albino. So for P generation you breed an albino x wild. Their offspring make the F1(First Filial) generation. These offspring will all carry one albino gene.





You then breed an F1 animal with another F1 animal to reproduce the trait. Their offspring are the F2 (Second Filial) Generation. Because F1 each had 1 albino gene the offspring will have, a 25% chance of reproducing the albino color (or lack thereof), a 50% chance of having one albino gene, a 25% chance of having no albino gene.





Hope that helps.|||its a reference to the snakes generation in a breeding project. it could also be used to describe how many gens. removed from the wild it is.|||You are correct. An F1 is direct descendant of an animal, either wild caught or a new morph. F2 is second generation.
