Vertebrate chordates differ from invertebrate chordates by the presence of the vertebral column.
<h3>Vertebrate vs invertebrate chordates</h3>
Chordates are of two groups - vertebrates and invertebrates.
The vertebrate chordates have vertebral columns which developed from the notochord.
The invertebrate chordates, even though possess notochords at some points in their life, do not have vertebral columns.
Vertebrate chordates include fishes, birds, reptiles, and mammals. Invertebrate chordates include the tunicates and the lancelets.

Answer:
The most appropriate explanation would be the presence of two types of melanin in hairs.
In human hairs, two types of melanin are present: eumelanin and pheomelanin.
Eumelanin determines the darkness of the hairs, that is, it would determine if the hairs of a person would be black or brown.
Pheomelanin is responsible for orange or red colors of the hairs. In addition, on breaking down, it provides the hairs with colors like red, orange, yellow and white (complete breakdown of pheomelanin).
