can you breed siblings?

1. They want to keep a certain line going...

2. Some may not be compatable. (axanthics for instant)

3. Who knows! LOL!


Just some possiblilitys.

most breeders with female morphs will do double-triple hets and combos and crosses with the female morphs!

Because female homozygous mutations are being used to create combinations .. for example, you can breed albino x albino and get 6 albinos at $1,500 a pop or you can breed a albino spider x albino and get 3 spider albinos and 3 albinos for even bigger bucks! I'll take door number 2 anyday! ;)

I dont remeber making the claim that the reason why there is so many varying mutations is because there is a relatively high population in a concentrated geographic region. I do remember reading it on this site before though....I think another user said that.....I think I just agreed with whoever that was.

And I still do agree with that person for two reasons....

First Large population size prevents genetic bottlenecks because a large population can have more variation in its gene pool than a small population.

2nd A large population concentrated in one region prevent subpopulations that inbreed (yes inbreeding does occur at times in nature) from occuring....this is one reason why landscape ecologists that work on the design of nature perserves often prefer one large area over several small areas that add up to the same size!
