Snakes born from the same parents will be brothers and sisters regardless of weather or not they are in the same clutch. They will have dif ages but the same genetic stock.

You should always consider carfully before inbreeding (breeding an animal to a near relative like mother, father or sibling. Even aunts, uncles and cousens.) as it can result in a higher likely hood of genetic disease. Cancer is one of the most common results of too much inbreeding. You see it in white mice and rats all the time.

Also a reduced resistance to contagous dideases like upperrespritory infections (colds).

If you do inbreed to bring out a trait I strongly recomend that the next generation be bread with compleetly unrelated stock.
