JJay, There are no known dwarf genes identified in the horse genome, meaning all horse breeds, compared to the dwarf genes known in the human. There are numerous known dwarfisms that are characterized and sequenced in the human, mouse, and cattle. These are what I am using to compare to as...

It is unfortunately impossible to know those numbers. This is due to the fact that some people do not admit that they have them, records are not kept on dwarf foals born, aborted or anything by the Assoc., so there is no way to know how prevelent these types are. I do have my educated guesses...

Ok, If you read my reply to Frank on the forum, I talked a lot about this. I do not have a "cut-off" I do not know what it would be or even how you could calculate that statisically, knowing that height is a quantitative trait, irregardless of the effect of the recessive gene, if any. Again...

Your question is a little confusing but I will try to answer it. "You mentioned in an earlier post on the main forum that there is more than one dwarf gene type. I know that dwarfism manifests itself in more than one way but I am thinking that is not what you are referring to. Or is it? Are you...

MSRminis, There are no known or proven environmental causes to any of the dwarfisms in the Miniature horse. The reason why this would be impossible for any of the dwarfisms to be due to a specific environmental factor is that it would have to be something to cause the exact mutation every time...

Carol, From what I have personally seen, no there are not any bloodlines that produce "more" dwarfs than others. It is spread throughout the industry involving all of the common foundation stock bloodlines with all of the different type of dwarfisms. Because this "breed" came from a...

Annette, Boy you picked a big one! The short answer would yes and no. But I will give you the correct answer. (Deep Breath) To answer fully your question I need to take into account all 4 possible types I have characterized so far, however there could be more types than these or one of these...

Frank, I would really like to sit down some time and have some discussions on breeding practices and genetic inheritance. Genetic inheritance follows statistical laws, that is well proven and explained in basic genetic books and breeding and inheritance books. What I want to know is why you...

MA, Which two types of dwarfism are you referring to? I believe there are more types than that. Can you explain to me what you mean by these miniatures having possibly two different genomes and how that is possible?? John

I am pasting what I wrote in another thread, like I said I would, this really doesnt talk about dwarfism, yet I think most of you know where I stand with that issue. On a side note, For those of you that have answered the thread with regards to studying genetics whether general, plant or...

I have quietly sat, and I must say, I have been intrigued with the conversation over a very touchy subject. I will try my best to stay on Ed's subject he wrote about, since some of us have strayed a bit. I'm glad now we ALL can admit that we have measured horses in that were a little above the...

Lewella, Yes you are correct in that the Icelandics were used initially for the isolation of a suspected gene for silver, however in order for this potential gene to be considered an actual color gene and not a different gene that is linked to a random color gene with the silver Icelandics, is...

Hello, I am pasting a letter that went out to the people that emailed me directly. I want all to know I DID NOT as a committee chair or otherwise recommend to disallow silver bay, it was already in the office as such when I became chair and I was unaware to me until last year what the new...

Thank you for including The Heritage Sale at Little King Farm May 26th in your post for sale information! I wanted to give the correct web address. www.theheritagesale.com I am in the process of posting photos of as many horses as possible for people to see in advance of the sale. New...

Nancy G, Actually I'm working on 4 different dwarf diseases, I hope I am able to design a test or tests that can be used large scale, sometimes a diseased gene is found but the mutation does not make it possible to make a large scale test, so we will see. To understand about recessive...

Jannell, I went back and read the article you referred to in the MHW. The article had some helpful info for that time. It was flawed in some respects regarding disease characterizations and nomenclature associations to horses. Also there are no known inheritable dwarfisms in any other horse...

Janell, The x-rays needed are very specific parts of the body, and certain views, meaning angles, that the x-rays are taken. My vet, the equine pathologist I am working with, and I worked on a specific protocol to use for the foals, we are going to apply it to the adult dwarfs, if other vets...

Targetsmom, are you refering to your mare that is GREY overo as a silver?? You do not need to test the mare for silver if neither parent is carrying the silver gene, the silver is different than grey. Some people refer to the typical color seen in the Mniature of silver as silver dapple gray...

I am assuming many things with your question, but I will try to answer the best way I can. First, I assume you are only talking about true grey and not silver dapple gray and that you know there is dappling in true greys that is the same as dappling in silver gray, but dappling is a separate...

This thread has obviously progressed to an interesting subject, one that if asked, everyone would have their own answer and opinion, unfortunately that IS what this is all about, everyone has their own opinion of type, including the judges, and so there WILL be variations of type, the goal is to...
