Biology Classification Quiz

One reason common names are not useful to biologists is that they

• are in Latin.

• can apply to more than one animal.

• are too long.

• require the use of a dichotomous key.

At any level of organization, groups that have biological meaning are referred to as

• cladograms.

• taxa.

• binomials.

• systems.

According to the rules of binomial nomenclature, which of the terms is capitalized?

• the genus name only

• the species name only

• both the genus and species names

• neither the genus nor species names

Often, the second part of a scientific name is

• a description of a trait or habitat.

• the same as for other members of the same genus.

• capitalized if it derives from a proper name.

• different in different locations.

When classifying organisms, a monophyletic group includes one

• species and all its ancestors.

• ancestor and all its descendants.

• species and its genus.

• genus and all its species.

The grouping of organisms based on their common descent is called

• traditional classification.

• binomial nomenclature.

• derived characters.

• evolutionary classification.

In contrast to Linnaean taxonomy, cladistic analysis considers only which kind of traits, or characters, for analysis?

• genetic characters

• derived characters

• lost characters

• physical characters

What does a cladistic analysis show about organisms?

• the importance of each derived character

• the relative degrees of relatedness among lineages

• the general fitness of the organisms analyzed

• all traits of each organism analyzed
