the advantage is not much greater. for example snowflakes. if you have a super snow pair that breeds you might only have a few extra super snows in the batch. im talking less than a dozen out of hundreds. most breeders makes sure the male is the prettiest and best fish to use cause most of the good genes come from the males. i have a pair of super snowflakes and 2 pairs of extreme snowflake males with regular occy females. my % of having nice snowflakes is about the same as them coming from the super snow pair.
