Could someone tell me the exact definition of a bloodline? I know it has to do with the parents, but what are the qualifications for multiple bloodlines? If you had 4 bloodlines, does that mean you have 4 pairs, or could it be like one female and 4 different males, or one male and four different females? Please help me clear this confusion up, because i've always wondered about that-- i'm not too good with Heredity and Genetics.

Thanks

Bloodline is basically, where they come from. Not the specific spot, but like their parents. Its basically, so you don't inbreed your dart frogs. Inbreeding can cause disorder genes. And may cause your frogs to be deform. I think this is what it means. You can ask other for advice.

well if you have 4 frogs and 2 are male and 2 are female, and none of them are related to eachother they come from 4 different blood lines. if you pair them off and breed them then the offspring will come from one of two bloodlines
in short your breeders are from 4 bloodlines and you produce two bloodlines
A,B,C, and D are each of the 4 frogs.

A B = ab
C D = cd

now you could take ab and cd and breed them together for another bloodline. baisicly any mix and match you can do without inbreeding is a clean bloodline. After a certain number of generations of animals being removed from the original bloodline you could mix them back without defect. Unlike people, darts and many other animals are not effected as severely by inbreeding. There is some research that would suggest that darts can inbreed for up to 10 generations without defect. I would be weary about going to those extremes though.

That was a very good post adamsanity. But I wanted to add that It may be true that darts can inbreed for 10 generations with no visible ill-effects, but it may take another 10 generations to begin noticing these effects. Im just relaying read information, so Im not sure it's true, but just play it safe and trade offspring with someone to keep the bloodlines clean. These gems are far to rare and beautiful to screw around with.

Most undesireable genes that cause metabolic problems and deformities, and all lethal genes (that preclude survival of the offspring) are recessive, meaning that they have to be inherited from both parents to be expressed. So the more breeding among related animals that goes on, the more likely these genes will pair up to express themselves. This is admittedly an over-simplification, but is pretty much the general idea.
