A couple of examples:
I have a unrelated pr het clowns. I breed those and produce a female clown. Then I have options. 1.I could trade her for an unrelated and breed her to my male het. 2.Could just breed her back to my male het(line breeding). 3.could breed her to another morph then breed those to my original two hets (grandparent to grand kid).
Rdr has a very reduced clown it must be from selective and line breeding.
I haven't heard a lot about ethics of snake breeding.
Economically and practically there must be a lot of dads to daughters going on.
daddy platty has to be this way. Right?
Sorry. Ralph Davis not meaning to pick on you. Love your stuff.

My personal example bought a citrus queen bee male. I don't want to breed it into my "normal pastel line".
So I put him to 2 normals and breed him to those females.
Dad to daughter is that to close for reptiles.

In a nut shell what does everyone think on this?
My personal opinion was to follow my example 1 above one the het clown and queen bee and avoid parent to kid crosses. But I also feel line and selective breeding has a place ie Brian Gundy's gold blush Mojave, beautiful.
