Genetics of blue chickens
« on: May 11, 2018, 12:36:56 PM »
Chickens with blue (not lavender...both are similar, but different shades of gray) feathers have genes for both black and splash (mostly white, with splashes of blue) feathers.  One blue (Bl) gene dilutes black feathers to blue.  Two blue genes will dilute black to splash.
Blue to blue does not breed true. 
Black to black and splash to splash do breed true and they are co-dominant, so black to splash produces all blue offspring but generally not show quality.
The following combinations are achievable:
* Blue X Blue = 50% Blue, 25% Black, 25% Splash
* Blue X Black  = 50% Blue, 50% Black
* Blue X Splash = 50% Blue, 50% Splash
* Black X Black  = 100% Black
* Splash X Splash = 100% Splash
* Splash X Black = 100% Blue


The same is true when breeding wheaten, splash wheaten and blue wheaten...but just consider the male’s breast color (black, splash or blue) for the various wheaten varieties.
