Whilst this lady may be well thought of and knowledgeable, it is only, at the moment, her opinion, not a proven fact.
No disrespect meant here, Jane but "The Appaloosa Project is an example of the "new genetics" in action with recent developments in molecular biology particularly with respect to gene mapping technology, it is now possible to find
genes in a way that was not previously possible. The projects team is composed
of two phenotype researchers Sheila Archer and Dr. Sponenburg , and a large
number of genotype researchers (Dr. Terry, Dr. Bailey, and Dr. Brooks, Dr.Bellone
being the main players at this point in time).
There is a worldwide effort underway to "map the genome" of many
animals, including the horse. "The Appaloosa Project" is connected to
that effort. The old paradigm was phenotype-based, that is, they had
only the physical appearence of Appaloosas to make their judgements
from. Now they are able to take phenotype evidence forward and verify
it in the lab, finding the actual genetic mechanisms involved in the
physical traits they observe.
The Appaloosa Genetics Project consists at this time of the following phases:
Phase 1 - The E-effect Study
Phase 2 - Genome Scan for Lp
Phase 3 - The White Pattern Gene Study
