Not that I condone either one (since I know little to nothing about these topics)... but I do have questions. How, exactly does in-breeding and line breeding help to produce certain colors. Is line breeding used just when there is only "one line" to create other lines that are very far from related? I was looking at some Best of the Board posts from years ago, and people were talking about in breeding not being bad when done correctly. I know there is a difference between the two, but not sure the details of it. Can someone clarify this? For instance, on thepetglider website, some of the white on white variations, how were the produced exactly? I have not seen them anywhere else but her site. Thanks to anyone who can help me out here! I'm not saying I'm planning on doing this, etc... I'm just curious. <img src="/ubbthreads/images/graemlins/nixweiss.gif" alt="" /> <img src="/ubbthreads/images/graemlins/question.gif" alt="" />

Inbreeding should not be done, too risky when it comes to health problems and birth defects. Line breeding is a good way to produce more of one variation. Line breeding is used because you know the gene is carried in those certain gliders. Obviously pairing the genes together, you will have more of the chance of producing the variation you are looking for. The white gene and the white tip gene are 2 variations that I know can benefit from line breeding... the other variations have a good amount of different bloodlines, so line breeding is not needed.

Inbreeding and line breeding are one in the same but it is the degree of the breeding that seperates the two from each other.
Inbreeding is breeding parent to sibling or sibling to sibling. This type of breeding is rather intense as one is able to achieve thier goal much quicker. But...it has drawbacks due to possible genetic problems with the line.
On the other hand...line breeding is to a distant relatives such as an aunt or uncle to neice or nephew to a grandparent and occassional parent. Thus one is able to obtain their goal at a slower pace....without compromizing the overall health of the animal. <img src="/ubbthreads/images/graemlins/thumb.gif" alt="" />

Thanks Judie, When you say inbreeding will make you achieve your goal quicker, can you give me an example of this?

She means that you will get the color quicker then in line breeding.

Obviously, but can someone give me an example of when this was done, or how someone did it to get a certain color?

If, say, there were only 2 BEWs available for breeding, then if you mated a sister to a brother, you'd have another BEW. But, if you avoid that, then you'd have to mate a BEW to non-BEW for a few generations before breeding back in the family, and it would take years to get them back to BEW, instead of a few months.

Sheila's "sunkissed" glider, Calypso... how was he produced? Or was it just random that he came out like that?

<hr /></blockquote><font class="post">
Judie,
I’d like to thank you for your time posting, your posts are very helpful.
I have a question about that comment. Why would inbreeding once be ok, but not to do it repeatedly? When females breed for a while with the same mate (say, sibling for instance) does their offspring they produce change over time? I would think if you could inbreed once with it being just fine then you could inbreed other times with safe chances as well. I am just curious as to how this would work, or why sterility would "eventually" come, but wouldn't happen if you only bred siblings once? I saw that your Shy Baby who produces a lot was produced by sister and brother (correct me if I am wrong, I don't have factual information, it's hearsay), also the BEW Saleen was produced from inbreeding of siblings and she seems fine as well. So I just wonder that if what you mean by your paragraph was sterility will happen over time with two sibling or likewise related animals, or if you meant something else, if you could clarify that would be greatly appreciated.
The reason I bring this up is I have a WFB with a leucistic diluted gene. I believe this gives her the appearance of a sun-kissed WFB mixed with cinnamon. I guess one could call it "white faced lion", if you will. I have been searching for a mate for her after finding out her beautiful mate she was with was neutered, and the gal I bought her from did not inform me of that.
Well, I have the chance to purchase a WFB who is very likely to be her sibling, he is about the same age as well. However after reading this post I wonder what you mean by sterility in breeding offspring, even if it were to produce prettier gliders in the outcome.
Thank you Judie. <img src="/ubbthreads/images/graemlins/heartpump.gif" alt="" />

When line breeding....only three generations count. The fourth is too far removed. Yes, ShyBaby and Saleen are a result of two hets who were a sibling x sibling breeding. This is why it is important not to inbreed his offspring for several generations. This type of breeding was a 100% genetic copy. Let's pretend now that ShyBaby was bred back to Saleen. Now we have increased the chances greatly of producing white because of another inbreeding. Now those offspring are bred back to the parents. Now we see the gentic pool starting to become real tight...running the risk of genetic problems. This is inbreeding to the highest degree. There was another breeder who had white. Her breeding program was quite intense with a closed gene pool for four years or so. Now...there only seems to be one line that does not have a problem with sterility while the other line...it does. The other part of a breeding program is...records. With these gliders the records have been lost so this makes it even more difficult for the newest breeder who has taken on the challange of correcting the problems even more challanging. Right now I have three whites. And they are paired to 100% Hets for leucistic. Two hets are unrelated to their partners and one het is related to his mate by his father being the great grandfather to one white. The idea is to produce white or 100% hets without inbreeding one another to each other. Then these offspring should be paired to normals to produce possible hets. Then breed the possible hets back to a white who is a aunt/uncle or cousins. This type of breeding is slow but should have good results for having a sound line of white gliders. The problem I see...with a few unknown breeders who may be in a big hurry to produce white....will choose the most severe and quickest way to produce white and if so...it will be done at the expense of the gliders overall health. One cannot expect to inbreed tightly for many generations and not run the risk of sterility or compromised immune systems in the end. After all...look at what has happened to some pedigree Dogs and Cats. And it did not happen overnight but rather many generations of severe inbreeding.

Okay, I have a question on generations; how exactly do you count 4 generations? Is it at second cousins that they are considered unrelated and can be bred together? I found an awesome chart Here: http://www.cuddleinternational.org/genetics/kinship.htmlthat explains how to do the removed part, etc, but I am still lost as how to count generations! I have two WFBs that have the same grandparents; I want to know, if their babies can be bred together. (These two are with different mates.) The babies will be second cousins, and from what I have read, that is okay to breed together.

My above reply was in reference to two wf blondes who are related by grandparents. The two wf blondes are paired to normals The result then of these two new pairs would result with offspring that would be second cousins that are fourth generation as the great grandfather was the grandfather of the orig two wf blondes which are first cousins. sounds a bit confusing I know. <img src="/ubbthreads/images/graemlins/roflmao.gif" alt="" />

2 1/2 yrs ago when I bought my first glider I also purchased a bokk ( all about sugargliders) in this book it says that you can raise families in a housing unit and they will not interbreed. Well, the book was wrong. One of my babies, she is about 1yr old has a set of twins in her pouch. But I do not know who the father is. It is either her twin or her father. Obviously the book was very wrong and I have since separated them, but what I am needing to know is if there will be anything wrong with her twins when they come out of the pouch. Please reply directly to my email add []blonde1@intellex.com[/]

Most likely not, but if they are male neuter them and if they are female, do not ever breed them. These babies should be pets only.

Line breeding is an invaluable tool that a breeder must use inorder to maintaing a rare color in the population. I have been documenting the leucistic geneology for the purpose of sharing it with other leucistic breeders so that they might be more informed about their particular gliders relation to possible mates to avoid unintentional inbreedings. There appears to be less than 5 lines of sugar gliders and this makes it very difficult to find totally unrelated breeders. Without careful records and continual updating of these records problems such as sterillity and mutations might end lines and eventually lead to the loss of that color in the United States population. The albino line is even more restricted. It is ok to line breed if you have the records of several generations and there are no signs of sterility or genetic defects. Once a genetic defect has occured the pair needs to be split up and not allowed to breed until the cause of the defects and the mode of transmission is discovered. The glider that is the carrier for that defect then needs to be spayed or neutered to prevent further pollution of the gene pool. If measures like this are not taken and breeding continues the glider will likly continue to pass the defect throught the population and it may effect the breedability of the line. Ushuaia

Right now the information is only available to breeders that own a leucistic or a het for leucistic. Ushuaia

<img src="/ubbthreads/images/graemlins/offtopic.gif" alt="" /> Ohhhh, well aren't you feeling special Chris? <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" /> You never asked me if I had any leus or hets, so I never told you, lol. I don't understand why it would really matter whether I own one or not? Some people just want to learn or are just plain curious. It can't be that hard to send the info in an email? <img src="/ubbthreads/images/graemlins/nixweiss.gif" alt="" />
Anyways back to the topic at hand <img src="/ubbthreads/images/graemlins/thumb.gif" alt="" />

Ern... wow. Chris, everyone is here to learn so why would you not be able to share your information with everybody? Are you saying that people who do not own leucistics are lesser or are not looking to learn as much about them as people who do own them? I'm sure plenty of people on this board would like to see what you have found.

Yeah I was thinking that same thing what if some people want to learn as much as they can about the leucistics so that they know what to do and how to do it and then they would get one? And I think everyone wants to know about all the white color gliders espically Leucistics!
P.S. If you guy were talking about me my name is spelled Kris but if not o well.
