You are correct, F2 is second Filial Generation. Technically to be considered F2 their needs to be relation between the clutches (ie line breeding) in order to officially be a filial generation. With that said, in the chameleon hobby line breeding or in breeding is something move consider to be frowned upon so a lot of breeders, including myself will stay away from doing so.
So, I'm calling these babies F2 because they are two generations removed from the wild but they are from 100% unrelated pairings. The ability to get a gravid WC female, get babies and then breed siblings would be extremely easy and not something I'm willing to do. I also didn't introduce a wild caught male into the captive bred population as in my opinion they would only be considered F1 again and would also make the process a lot easier. To achieve this little baby, I started with four unrelated WC adults which each produced two unrelated clutches of CB babies. I then raised those babies up to adult hood and bred them as unrelated pairs and now produced unrelated, second generation, two removed from wild offspring. Hence why it took just a little over four years to accomplish.
To date, I have four unrelated captive bred lines that I produced and one captive bred line from Kevin. If all goes well over the next year or two I hope to achieve F3 with all unrelated pairings!
