SCIENCE NEWS: IYAK Genetically Outperforming Tibetan Yak

IYAK genetics: Remarkable, exceptional and wild!

Our registered animals are out-performing the Tibetan domestic and wild-types on several genetic and phenotypic fronts. Its a very special population in the world. IYAK is a truly unique and valuable herd. UINC estimates indicate Tibetan wild yak are "Vulnerable" and dropping 2% per year (2014), and new counts suggest wild yak may already be endangered. IYAK may soon be the last strong hold of the original, ancient and pure genetics (if we continue to protect it)!

The reddish cast may be due to modifying or casting genes that act in the presence of the primary black gene and interaction with sunlight to create the reddish cast. This can also be seen in Black Angus cattle, Friesian horses and many other livestock breeds.
