Brown or Black?

This album contains photos of brown and black foals who have been tested for Agouti. Black foals will test aa while brown foals, if tested by PetDNA Services, will test as AtAt or Ata . If other labs are used the results will be returned as Aa or AA since only PetDNA distinguishes between A and At.
