Let us first define what line-breeding is. line breeding is breeding animals related by two or more generations. for examples,
cousins to cousins and grandmother to grandson is both considered "line
breeding". Next, Inbreeding is breeding of two animals that are related
by one generation. most common inbreeding people use is parent to offspring breeding.
Now, why do people Inbreed and Line-breed?
inbreeding and line-breeding is used to "fix" a trait that is seen in the
line. line breeding takes more time, and inbreeding will give you a faster result, but both practically has the same purpose.
You
would always hear breeders and experts saying "DON'T INBREED/LINE-BREED".
this is true for most of you for line-breeding and inbreeding fix not
only the desirably trait, but also the undesirable ones. thus, if the
line is known to have a slight deformity or health issue, line-breeding
and inbreeding will magnify and accent the issue. also, excessive
inbreeding and line-breeding will result to handicap and major
deformities due to the small genetic pool that was used to create the offspring.
Lastly, WHO COULD INBREED/LINE-BREED? inbreeding and line-breeding should be left to the experts who knows every detail of the
family's genetic pattern and health issues. the reason that this practice
is left for the experts is that, most experts tend to have kept the
individual's family for generations (usually even up to their great
great parents), thus they will know what to expect and not to expect.
they would be the ones to weigh the pros and cons of breeding this
individual to a relative, and would decide if it is worth it or not.
INBREEDING AND LINE-BREEDING SHOULD NEVER BE USED AS A WAY TO SAVE MONEY AND SPACE TO BUY RARE AND PRICEY ANIMALS.
Well I agree with you at the very least. I believe that there is no problem with INBREEDING. Yes it is true that they have pros and cons but even if you breed unrelated, pros and cons are present too.
TumugonBurahinIt is not true that if you inbred hamsters there is a large possibility that the litter will be deformed or weak. No. It is a genetically problem that has nothing to do with inbreeding. Even mankind produced deformed and babies, as well as animals. It is a health problems.
It is true that they will inherit their parent's illness, so you shouldn't breed an ill hamster in the first place. And if you breed the offspring of the ill hamster to unrelated hamster, you're just spreading it.
They are all inbred in the wilds, if you just look at the family tree of animals they are all started in just a pair when the world begins then multiplies, so inbreeding takes place.
Even mankind before inbred then yeah we multiply, you are alright, and i think i am too. No defect and such, but others has and it is not ancestor's problems.
