Question

Choose the correct answers from the alternatives given .
A classification that purports to demonstrate phylogenetic relationships must be based on characters ..........

• A. Homoplastic
• B. Homologous
• C. Analogous
• D. None of these

Answer 1

The correct option is B Homologous

Homologous characters in different organisms that are similar because they were inherited from a common ancestor that also had that character. Phylogenetic relationship refers to the relative times in the past that species shared common ancestors. Hence homologous characters can be used for purpose of classification to demonstrate phylogenetic relationships.

So, the correct option is 'Homologous'.
