Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a backbone or spine), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include arthropods (insects, arachnids, crustaceans, and myriapods), mollusks (chitons, snail, bivalves, squids, and octopuses), annelid (earthworms and leeches), and cnidarians (hydras, jellyfishes, sea anemones, and corals).

<em>The correct option is B) Both would be represented as completely shaded squares.</em>
Explanation:
A pedigree can be described as a chart or a diagram which reflects the occurrence of a particular phenotype from one generation to another in a family. It determines the family history for a trait.
In a pedigree, males are usually drawn as squares. A male who is carrying a disorder or a particular phenotype under study is represented by shading the square. A male who is a carrier for the trait under study is represented by lines on the square. Hence, option B is correct.
