URGENT!!!! Need help with info on PHA, TH, and AM for school paper!

[MYT Farms]

I know this has been asked countless times before, but I need information on the PHA, TH, and AM diseases. I need to know what breeds they originated from, but mainly on PHA and TH. AM I know a little more about, but I am fairly clueless on PHA and TH. Any books, articles, webpages, etc. would be greatly appreciated. Thanks.

an angle you might want to add, is looking up the TH gene in other species.  the gene for PHA is not yet published, but is known.  remember to emphasize that these are autosomal (not sex chromosomes) recessive genes, ie, they have a carrier status, and a lethal status and that most of the rancher population still can't understand this concept.  imagine trying to explain a defect that has more than one gene.  these types of genes are low hanging fruit.  also realize you can have an early stop codon at ANY point in the gene and you will still have a defect as long as it's in the open reading frame.  other mutations can occur outside the open reading frame, and some of these are viewed as beneficial, such as one of the tenderness markers which is in the downstream end of a gene OUTSIDE the open reading frame.  there really is no reason for PHA and TH in commercial herds other than stupidity and/or ignorance.  show herds, that's another story.

"The battle of the bull runts" is a neat little book describing the herfords battle with the dwarfism problem they faced in the early and mid 1900's.
