Compared to the Blue Cochin, why does maintaining the Blue Andalusian color require a more active genetic pursuit?
Answer
The Andalusian requires breeders to intentionally manage the presence of the Splash and Black extremes to produce the intermediate Blue.
In the Andalusian, breeding two Blues yields three colors, necessitating management of the extremes (Black and Splash). In contrast, the Blue Cochin's color is often governed by a simple recessive gene where breeding blues usually results only in blues.
