Hi there, was just wondering, it looks like a lot of people interbreed there mice?? is this safe and should it only be done with certain varietys?? From what i know of i dont think you can get deformed mice (if they are inter bred) was just wanting some more info???

from what ive heard, you need to interbreed (brother to sister pairings) for 60 generations to get a pure colour gene. start getting problems at 100 generations.
some lab report i read. if that holds any weight or not im not sure. you can definatly in-breed for some time. its not a bad thing with mice

ahhh ok thanks for the info. i just wasnt too sure.

I think you mean inbreeding; it all depends on the history of the lines you are dealing with. If there is a long history of good health in a line there's no reason not to inbreed. that's how showers of fancy mousie maintain the purity of their lines. If you are dealing with petstore mousies, there's no way, usually to determine the health of the mousies, and it's best to avoid it if possible. This is especially true with any newer recessive varieties like rex, hairless, satin, etc., which are often hard to get at a petstore, but they do show up from time to time.

If you get meeces from a reputable breeder who can vouch for the soundness of the lines, or the lack thereof, then you'll be informed on how to prceed in making pairings.

Well said, moustress.

Inbreeding should be avoided unless working with a well known line.

Ok thanks guys

Dont use the words in breeding. use the words breeding in. now it will make sense. Breed close relatives who both share the same feature together. If you breed two mice with the same fault together, you will give inbreeding or breeding in a bad name.(This fault can be lack of vigour, por fertility, etc ) The results are up to the breeders. It takes two generations to fix a true breeding colour. You can closely inbreed for thousands of generations if its done right.

I'll be back:

Respectfully, I must disagree with your statements.

Inbreeding is the correct term; linebreeding is another correct term. Whether you do either or neither is individual choice. I think you have overstated the degree to which either can be done without perils. Random mutations can occur at any time, and in captivity it's more likely to be a harmful thing than in nature where only those mutations that are beneficial and promote continuance of that line are passed on.

I did not say it wasnt the correct term, I do not recall linebreeding being mentioned either. Nor do I recall mutations being mentioned either. What are you on about ? Perils are in the hands of the breeder. We were not talking about nature.

 

[moustress]

Looks like I didn't understand what you were trying to say. No worries.

sorry guys didnt mean to cause havock :? was just curious

 

[george]

id ignore my previous post. thats just what ive read from lab reports. sounds like youve gotten proper advice from some experienced breeders there

thanks for your input tho
