In BPs breeders go by the paternal line not maternal. Personally if I had a really nice looking normal male I would breed it. It wouldn't be to a really expensive female. Maybe a single, or double gene girl like a pastel pinstripe girl. Then you can get normal, pastel, pin and lemon blast (hope that's the right one. Haven't had coffee yet.) I'm a person that's more interested in maternal lines.
So why is it only female normals can be bred, but you can't take a normal male and breed it to something different? What's the difference?
The difference is you're wasting the potential of any female by breeding it to a Normal male.
It is not wise to breed a genetically inferior male to any female. Breeders generally use a 1/2/3 gene female and throw a genetically superior male to them. One double, triple or quad male can service many 1/2/3 gene females.
Spend your money on the best genetic male you can afford that fits into your projects and pair him to 4-5 females.
