Just browsing around through some sites today and something makes me wonder.

Pastels are a Co-Dom trait. Therefore if I someday breed our male Pastel to a normal female there is a possibility of 2 pastels and 2 normals (based on the punnet square). Of course I realize nothing is ever a given with genetics.

Now those normals are "just" normals, correct? Nothing different genetically then any normal, right? So why do I see ads for "pastel siblings"? What would it matter if they are siblings to a pastel as they don't themselves express that gene or have the ability to carry that gene to their potential offspring? Why would someone advertise them that way?

Also is my understanding correct in saying that a Pastel being a co-dom is basically a visual het of the Super Pastel? So the difference between simple recessive and co-dominant is just in that the offspring can be visually sorted? Or have I way oversimplified this?
