Well this is pretty much my first post;in addition, my first question.
I've done a lot of research on koi and own couple of koi myself.
(Kohaku 10" with a beni on the head "lip to pectoral fins and a hi dot on the border line between the end of the body and the caudal fin," showa 4-5", but without equally distributed lines and a beni on the side head surrounding the eye, a sanke 3-4", kohaku 4-5" unique pattern, and a doitsu kohaku which has a non-se-metrical square between the eyes not even passing the pectoral fins and stops at the nostrils, but with "hi" lipstick on the lip, and a dim circle that is transparent on much of the body side and introducing a bit into the Dorsal fin.) I will eventually post pictures of my fish.
"Now let's get to the point"
I've been wondering if the same concept about breeding two kohaku which has a better chance of getting a tancho can also go with other koi varieties? Basically my question is, do you have a better chance of of getting quality offspring by breeding two quality parents rather than breeding two non-quality parents with quality bloodlines?
