Remember that every option branches into two new options only, and that you want to avoid redundance in statements. In cases where a key refers to the presence or absence of a trait, one may use yes/no statements. However, the presence or absence of a trait may not necessarily be the case for this key, in which case you will find using descriptive statements more logical than using yes/no statements (you will have to figure out what works best).
