agree, however exception are some light colour breeds are easier to achieve by breeding intermediates.
eg.
two intermediate albinos breeding will produce 25% albinos 25% without albino genes and 50% albino intermediates.
reason to breed albino intermediates are that albino parents cannot darken their bodies to attract the fries to stick onto them to feed off their body mucus.
so a lesser percentage will survive if you breed two pure albinos.
there is also the importance of strenghtening the gene pool by outcrossing with wild fish...this results in a lot of intermediates again...which is dumped into the local market...
