why not instead breed
buf X amel
buf X lavender
buf X bloodred
AND
toffee X amel
toffee X lavender
toffee X bloodred
hold back all offspring
breed f1 sibling X sibling
and then compare how the toffee amels compare to the buf amels?
and so forth.
I do not understand what breeding 2 similar looking baseline classic morphs is supposed to prove.
