Question

Which group shares most common characters with each other?

• A. Members of the same kingdom
• B. Members of the same genus
• C. Members of the same phylum
• D. Members of the same class
• E. Members of the same family

Answer 1

The correct option is B Members of the same genus

The seven essential ranks of taxa in the descending order are the kingdom, division/phylum, class, order, family, genus and species. The number of shared characters decrease as one moves towards the higher ranks. Therefore, among the given options, members of the genus will exhibit most common characters with each other which will go on decreasing when we move towards the kingdom.

Thus, the correct answer is option B.
