I can add a few other interesting questions while we are at it as well......
Why, in the heterogeneous state, when it co-exists with the Snow White gene, do the coloration always take place on the lower half of the fish? example red/white yellow/white...
Why, when combined with the BD gene does this pepper go from black to blue? Is the BD gene and the PB gene actually different mutations of the same gene?
