They actually would result in 100% het pied and pastels that are 100% het pied.

Pastel is a co-dominant trait, with one allele being for pastel and one allele being for normal. The babies that inherit the pastel allele will be pastels, the ones that inherit the normal allele will be normals.

Pied is a heterozygous (or recessive) trait - which means that both alleles have to be pied in order to get a visible pied. So, all the offspring of the pastelxpied will recieve ONE allele of the pied, and all will be 100% heterozygous because all will get 1/2 of the pieds alleles (and the visible pied has TWO alleles for pied), so all the offspring will carry one allele for pied, which makes all the offspring 100% het for piebald.

So the offspring of piedxpastel will either get a normal or pastel allele from the pastel parent and all will get one allele of the pied from the pied parent.

Normal gene + pied gene = het pied
Pastel gene + pied gene = pastel het pied

Are you more confused now?
