When breeding Appaloosas, part of the registration is parentage DNA testing. It involves pulling mane or tail hairs (with roots) and sending to an Animal Genetics Lab, the certificate is then sent with the registration documents and the results clarified with the dam and sire’s DNA on the breed association database.
For our own satisfaction, we like to know “for a fact” what Appaloosa genetics our foals have inherited. We requested the combination panel of Leopard Complex, Pattern gene, Base Colour, Cream and we decided this year to check for Dun!!!
So here are the results…
Homozygous black (EE aa) few spot (LP/LP) colt with one copy of the Pattern gene (PATN1/patn1).
Bay (EE Aa) with one copy of Cream (CR/cr) making her a Buckskin, she’s a few spot (LP/LP) with one copy of the Pattern gene (PATN1/patn1).
Homozygous black (EE aa) with one copy of the cream gene (CR/cr) making her a smokey black near leopard filly. Heterozygous Leopard Print (LP/lp) and heterozygous Pattern (PATN1/patn1).
Bay (EE Aa) with one copy of cream (CR/cr) making him a buckskin leopard. He’s heterozygous Leopard Print (LP/lp) and homozygous pattern (PATN1/PATN1). Reflection is the reason we chose to test for the Dun gene, his phenotype is quite unique in my mind and as it is with Appaloosas, they always surprise you! Very much curiosity but the results proved his dam Caricks Redheart carries the gene nd1, a gene found in Dun’s that can show primitive markings (nd1/nd2) not to be confused with the Dun gene that affects colour dilution.
Now that’s a surprise!
