"If you breed recessive gene male to a normal girl you can still "back him up" with a codominant male like a spider. That way if all the babies look normal chances are the recessive male fathered the clutch. If you see spider in the clutch it's obvious the spider fathered the clutch. Spider (codominant) x normal = half babies spider and half babies normal. Pied (recessive) x normal. all babies look normal, but are 100% het pied. Hope this helps. Chris Hall"

With the above situation you have no idea if the normals are het or not. It is just a guess, even if there are no spiders in the clutch.

I have spoke with many people at shows that are selling hets, when I've asked about the parents and what was bred, sometimes they are hets and sometimes they are just possible hets. Some people believe a het to normal makes 100% hets, some believe het to het is 100% het, obviously neither of these breedings results in 100% hets. Other times there is the question of multiple males and not knowing for sure which male fathered which egg. These aren't people trying to hide anything, they admit what the breeding was, they are just incorrect in assuming they have 100% hets.
