Line breeding

not the way i understand it... unless you happen upon a gene you didnt know was there...
line breeding is just breeding normal animals of different than average color to try and create more of that difference.
like halloween milk snakes. Thats not a gene..well it is but it's not as easily mapped as something like albino...its just luck. by selectively breeding milk snakes with smaller or fewer red bands over time they very slowly manage to get rid of them entirely...but not always..... two perfect halloween milk snakes will still produce completely normal babies but have a higher chance of passing on their patterns and tendencies to have lower amounts of red bands.
where as morph breeding you are working with distinct known genes. if you breed a normal to an albino you WILL get het albinos.... of course with triple hets and co dominant traits and all that jazz it certainly gets more difficult but it is still much more predictable and set than line breeding.

False. Line breeding is the breeding of related animals in effort to make a trait more stable. Usually it's father daughter, then same father to daughter of daughter, etc. Just randomly grabbing two animals that look similar and breeding them is NOT line breeding.

-Selective inbreeding to perpetuate certain desired qualities or characteristics in a strain of livestock.
-a form of inbreeding directed toward keeping offspring closely related to a superior ancestor.

Your talking about line breeding to maintain a certain genotype versus line breeding to maintain or develop a specific phenotype. We do this is mice and rats all the time. You essentially breed closely related animals together through several generations slowly homogenizing the genotype and reducing the odds of variation outside of spontaneous mutation. You are basically trying to produce genetic clones. It can be done for lots of generations and still maintain some phenotypic vigor, especially in herps. The danger comes when your particular strain becomes susceptible, and exposed, to a certain pathogen and then your whole bloodline is at risk.
Syl, this statement is correct. Line breeding is inbreeding. This is the simplest way of putting it.knifegill;4946222; said:
Say i have animal A. It has a very odd gene i want to highlight. I breed it. I breed it to its offspring in an attempt to bring it out a little better in the next generation, so on and so forth.
I think i remember someone line breeding leo rays awhile ago in an attempt to create some extreme oddball leos. It ended with some insane leo(which are usually black and white dots)
