Isn't this wrong?

While at work today I was browsing some FS threads.

As for his color, none of the offspring show it as of yet. There could be something else going on. I kept back 1.2 of his offspring for myself to breed back to one another.

To me it sounds like inbreeding. Since I have been considering breeding lately I just assumed something like this is wrong. Is this something that is OK and I have just thought wrong?

Inbreeding in reptiles isn't the same as inbreeding in mammals. It is common practice to "line" breed to try and isolate certains traits in the offspring. Its also used to try and prove out a morph. You shouldn't really inbreed more than a generation or 2 tho.

Yup. Reptile inbreeding doesn't show the same negative outcomes as mammal inbreeding. But even mammal inbreeding won't show any defects or mutations right away. It takes more than a few generations of inbreeding for problems to occur.

Yes it is inbreeding.
No, there's nothing inherently wrong with it.

With some recessive traits that people are unsure about, they breed back to the same line to "prove out" the trait as being genetic.

Technically "line breeding" is breeding to another animal in the same lineage(mom to son, dad to daughter, aunt to nephew, etc). If there is any unwanted genes, it can "double up" and be expressed or expressed more. If there are wanted genes, same principle.

Wow thanks! So if you maybe want to enhance a color or pattern then you may want to breed back to the parent if I understand correctly.

Yes thats correct. And I agree with Zombie, I would not do more than 2 gen or so...

Like others have said, inbreeding it's a huge issue in the reptile world, in any world for that matter, unless you inbreed generation after generation. It's openly accepted that a generation or two is a fine practice. I'm going to guess that some people inbreed more than just a couple generations so when getting a sibling pair keep that in mind.

Completely agree with this! I think this slips some minds. Something definitely to pay attention to and consider before breeding. This is where accurate documentation of lineage is important.

Honestly this is what had been bugging me about morph breeding [especially "Super" types] for a long time; I still don't think I'd be comfortable purposely inbreeding/linebreeding if I had my own, maybe I'm weird ^^;
I do recall, a few years ago, stumbling onto a GTP or Emerald Boa breeder's webpage back when I was reading up on snakes, and they had a lot of hatchlings for sale that were missing one or both eyes, which I thought was caused by inbreeding so that was a huge turn-off for me ._.

Thanks for this thread and all the informative replies, I understand a bit more about this sort of issue now :3

Line breeding as been done with reptiles for generations with no ill effects. Line breeding is done to prove out animal's genetics, for certain traits, etc.

There is a big difference between reptiles and warm blooded animals but it all comes down to line breed DESIRABLE traits

Why only 2, does something happen when you breed 3 generations :confused:

All jokes aside if I remember correctly I believe Leos and Corns have reached their 20th generation.

Line breeding/Inbreeding is not that big evil some people make it out to be also does not mean you should not bring in new blood when you have the opportunity to do so.
