Arabian horses and d1 (nd1)

On November 10, 2018 by breeding.horse

On June 28, 2018 by breeding.horse

This one is a common question: buckskin or not? This filly’s coat varies from season to season. We’ve tested her for agouti, red/black, cream and dun/d1 (nd1) to find out. Responses on this one were roughly equal for buckskin vs. not buckskin….

Mystery Solved! May 2018

On May 30, 2018 by breeding.horse

SB1 + W20 horses: Case study two

On March 16, 2018 by breeding.horse

We’ve already shown you one example of how much white you can get when a foal inherits a copy of sabino 1 from one parent, and a copy of W20 from the other. Here is our next example: Tahmathor Park Colonial Jasper….
