Serjio, no, a recessive trait is one which can skip a generation and someimes many generations. It simply can't manifest until two such genes are finallly paired up in an individual. So the parents of your cross each need only be (unaffected) carriers of the recessive gene. And if that's the case, 1/4 of their children will get the two ressive genes needed in order for them to manifest the trait. If both parents are manifesting the plicata trait (homozygous recessive for plicata) then 100% of their children would be plicatas.
It is a dominant gene that can't skip generations. Where present in an individual it always manifests. It can't be hidden and skip generations. It can be masked however, by a (generally) darker colored dominant gene in a different allele location, or in the same allele locaton in the other same-number chromosome.
What I've said above assumes diploidy, and I know that the percentages would be altered by triploidy and tetraploidy.
