Current Question (ID: 11790)

Question:

Which of the following statements about classification is not true? I. Members of a family are less similar than members of an included genus. II. An order has more members than the number of members in an included genus. III. Families have more members than phyla. IV. The number of species in a taxon depends on their relative degree of similarity.

Options:

1. Only III
2. Only IV
3. Only II
4. Only I

Solution:

Families do not necessarily have more members than phyla. In the taxonomic hierarchy, phylum is a higher rank than family. Phylum represents a major taxonomic group that includes multiple families, while family represents a group of related genera. The number of members in a taxon, such as family or phylum, can vary greatly depending on the group of organisms being considered.
