Becky Pelton, from SC, has been working on erminette Ameracuanas for 14 years.
A search on Classroom @ the Coop for “erminette”, a few months ago, brought up this post talking about both the ermine and erminette varieties.
“Ermine is the same as the columbian variety, and is found in various European breeds. I would say this pattern was named "Ermine" in Europe before the American breeds were developed, later named "Columbian". Then later again, the main gene responsible for this pattern was identified & named Co - Columbian. These breed true.
There is another variety called "Erminette". This is a totally different pattern, & different genetics. Erminettes are black and white splashed, usually white based, with black splashes all over. The Erminette gene is incompletely dominant, so yes, doesn't breed true.”
F. B. Hutt used the symbol "Er" for the erminette gene (not to be confused with E
R).
Erminette is like dun and blue, in that it doesn't breed true.
Erminette X Erminette = 1/4 black, 1/2 erminette & 1/4 splash erminette chicks.
Erminette X Black = 1/2 erminette & 1/2 black chicks.
Erminette X Splash Erminette = 1/2 erminette & 1/2 splash erminette chicks.
Splash Erminette X Black = 100% Erminette chicks.
I use "splash erminette" to describe the true breeding variety when a chick inherits two copies of the Er gene. I assume these pure (Er/Er) birds would be mostly white with black spashes, but not nearly as much black as the heterozygous erminette variety. If there is already a name or better name other than splash erminette, please let me know.
The variety with two blue genes (Bl/Bl) is called splash or splash blue.
The variety with two dun genes (I
D/I
D) is called khaki or splash dun.
