Double Het Pied, Albino?

[Eric Alan]

I thought heterozygous meant the genotype existed but the phenotype didn't show?

That is correct for truly recessive traits.

So there are markers to predict het traits?

Therein lies the catch. Some of the recessive genes in this hobby likely aren't truly recessive at all (by the letter of the definition), otherwise they wouldn't show the markers that we're referring to. Aren't genetics fun?
