When breeding 50% x 50% the resulting offspring may be Homozygous (visual morph) indicating that each parent animal is fully Heterozygous for the given trait.

However, if no homozygous offspring are present...who knows? The male parent may be Heterozygous and the female Normal, the female parent may be Heterozygous and the male Normal, both parent animals may be completely Normal, or both parent animals may be Heterozygous but the odds were against you in this clutch. You may never know which parent animal is Heterozygous...if either. And proving them Heterozygous or Normal could take several years.

This is why most recommend that at least one parent animal to be either Homozygous or Heterozygous. This way you only need to prove out a single parent animal...which takes a lot less time.
