Phylogenetic classification considers fossil evidence, genetic information, and common ancestry to classify organisms.

Which of the following statements about molecular taxonomy is correct?

It classifies organisms based on genetic and molecular similarities.
It only uses physical traits for classification.
It does not help in evolutionary studies.
It is not useful in modern taxonomy.
1

Molecular taxonomy uses genetic and molecular data to classify organisms and study evolutionary relationships.

Which of the following statements about taxonomic hierarchy is incorrect?

Kingdom is the highest rank in taxonomic hierarchy.
Genus is ranked higher than Family.
Species is the most specific rank in taxonomy.
Phylum includes multiple classes.
2

Family is ranked higher than Genus in the taxonomic hierarchy, not the other way around.

Which of the following is incorrect about binomial nomenclature?

It consists of two names: Genus and species.
The species name is written first, followed by the genus name.
Scientific names are always written in italics.
It was introduced by Carolus Linnaeus.
2

In binomial nomenclature, the genus name is written first, followed by the species name.
