Mona, Please reread out loud what you quoted me saying, I think you are confusing yourself. QUOTE Also, breeding carriers to non-carriers will NEVER produce a dwarf. The non-carrier only give normal genes, and the carrier will only give a dwarf gene 50% of the time; so 50% of the resulting...

They wouldnt be Linked as per the true genetic definition of gene linkage. BUT What this situation COULD be is that the type of horses we are breeding for MIGHT and I stress MIGHT, MAYBE or POSSIBLY, and HYPOTHETICALLY. You get my drift, anyways, those characteristics could be traits from a...

No, too many variables. The breed in and of its self is very problematic when you try to correlate something like that. We already know there are higher rates of dystocia than a large horse breed, irregardless of dwarfism present in the foal. We know that Miniatures have a higher incidence of...

The facility is Arion Mgmt. my farm. And I do not really want or need to house carriers, I have some already and I have numerous breeders that house their own already and give me blood donations. What I have done is take a dwarf at times, depending on type and age, to study growth of the...

"I have a question..do the genes have to match in order to produce a dwarf?? Like One horse carries gene A and is bred to a horse carry gene B..this can produce a dwarf? or do they both have to carry gene A?? Or does that produce differnt types?? Sorry..full of questions" I dont really...

John, "1. In your opinion are the majority of the animals you have worked with heterozygous animals for the trait of Dwarfism. and as such can a simple pundit's square be used once we know the specific genetic markers that constitute these traits?" To answer your first question, Yes, the...

First what usually happens in all animals are known genetic mutations that occur that are referred to as non-deleterious or silent mutations, which occur all over the body including in germline cells, ie sperm and egg cells. They are usually harmless to the organism. However sometimes, there...

I recieved this PM below from nightflight suggesting all of ACH cases in humans has been proven to be solely derived from the paternal side, ie, sperm only. This paper she sited I have listed below and it is available to read as a pdf, and other formats free. It was written in 1998. My...

"How does the development of the dwarf fetus differ from that of a normal mini? At what point could you visually see the deformities? Could these be seen on an ultrasound? Do you have any photographs of aborted dawrfs from various stages of development? At what point in development can you see...

I cannot comment specifically on your case, I would have to know first hand with the vet. But in humans certain dwarfisms cause the magnum foramen to be misshaped and restricted in its function causing breathing problems in humans. Human with certain dwarfisms have to have surgery to correct it...

You can put the photo up here but with out a pedigree, I cant give you anything other than maybe as an answer, if you want to PM the pedigree I can give you a better idea of somethings, and certain info I will have to PM you, but general conformation I can comment on but it will be...

"I know you are still in early stages of your research, but I was just wondering if you think the method of inheritance for achondroplasia is similar to what we've discovered in humans? Is it still a possibility, or can we rule it out?" "To save you the time typing it out for everyone, in...

"I have known SEVERAL farms that had mares with a thyroid imbalance and every one of them produced a dwarf foal. The mares were not on thyroid meds during the time of pregnancy. When the horses did not resettle, it was discovered it was due to low thyroid." There are certain types of...

You are being a worry wart, sorry to tell you. Yes, there are carriers of the dwarf genes that I see are stocky or heavy boned, but I see just as many that are extremely refined. Personal example, I foaled out a mare about 8 yrs ago that was a retired mutiple world champion, extreme in all the...

You might want to ask the Canadian club about that for my Feb. seminar. I still havent found the genes yet, so all samples are welcome just some samples that have or get which have all the things I need will be able to be used now instead of later. The more I have the better! those samples...

"Is there any documentation currently available regarding the number of dwarves born in the US in the last year? I know the answer is probably no but thought perhaps you have been able through your call for help with this study to have some kind of ball park figure. Thank you so very much for...

"Do you feel that continually breeding the same lines to each other contributes to dwarfism?" wpsellwood, To strictly answer your question yes, it is now and will continue to contribute to dwarfism. Why?, It is due to the same inferior genetics being stirred continuously in a festering pot...

targetsmom, If you refer to Annettes question that I answered it will help you. But I can say that there is no specific list of characteristics to stay away from, unfortunately. I wish I knew those answers!! Type one can have carriers that have some expressivity of the recessive gene, but...

Liz, "Could you summarize for us the most common health issues associated with dwarfism? Also, what is the average life expectancy (I assume it is significantly shortened)?" The only common digestive issues that I know of for all of them except the type 2, is colic, impaction, and...

Susan, OKay this is going to be more of my ethical and caring, personal opinion and less of my scientific opinion. Science opinion would be to not breed them, the quicker they are removed the quicker we can breed dwarf free Miniatures............., HOWEVER and BUT!!!!!!   We cannot...
