Based on the information that Cody's mom has heart disease, the most likely prediction about Cody's health is: Cody will have a higher likelihood of heart disease than everyone else.
While heart disease can be influenced by genetics, environment, and lifestyle factors, having a parent with heart disease can increase one's risk compared to someone without such a family history. However, it's important to note that it does not guarantee that Cody will definitely have heart disease.
