If both parents do not display a certain phenotype for a genetic disorder but have offspring that do the parents are most likely

The parents can still be the parents. When it comes to phenotypes a parent can display something like blue eyes but still have the genes capable to make a child with brown eyes. For example like this chart. Both parents flowers are purple but still have the genes to make a white flower as offspring. I’m not sure exactly how to answer this question I’m sorry. I’m not sure if this helped or not. You might want someone else to answer.
