Citaat:Dun Zygosity Testing
The specific mutation that causes Dun has not yet been identified, and there is no direct test for the gene. VGL has identified DNA markers associated with Dun that can be used to determine if a horse has the Dun gene and how many copies. The Dun Zygosity analysis is not a direct DNA test, so the following additional materials should be included to provide the most complete analysis:
Materials
1.Photos of the subject horse
2.A hair sample pulled from the mane or tail of one or both parents of the subject horse
3.Three generation pedigree of the subject horse
If a sample from a parent is not provided, the analysis may not be conclusive for the presence/absence of the Dun gene.
