Out of curiosity I decided to run Neogen Breed Seek on one of my Dexter calves. It's only a $5 add-on; so why not? I realize Dexters are not one of the 20 tested breeds. It's still interesting to see what DNA is shared between breeds.
The calf selected has full Dexter G5 pedigree verified by PV. The results are interesting. The primary breed is Red Angus 18%, second is Hereford 17%, and 67% other. It is not surprising that Dexters share DNA with other British breeds. Kerry and Devon are not included in Neogen comparison.
If you look at the literature, Timothy C Bray ran a detailed analysis of Dexter genetics for his Phd Thesis (2013). Dr Bray's results show the primary genetic contributions came from Kerry, Devon and Aberdeen Angus.
BreedSeek delivers breed verification results by identifying primary and secondary majority breeds and percentages represented in an animal for 20 breeds.
