Nonmetameric → It is formed from "non-" (meaning not) and "metameric" (from Greek "metameros", meaning having parts or segments). The word "nonmetameric" describes something that does not have parts or segments that are similar in structure or function.
Think of 'not' ('non-') having 'parts' ('metameric') — that's why nonmetameric means something that does not have similar parts.
