Question

Select the group which shares the maximum number of common characters
A. Two species of a genus
B. Two genera of a family
C. Two individuals of a same species
D. Two genera of two families

Answer 1

Hint: As we go down the group in the taxonomic hierarchy the number of characters decreases. Species is present in the down of this hierarchy but present in the top of the pyramid.

Complete answer:
Taxonomy is the branch of biology that consists of the process of classifying different living species.
A taxon is referred to a group of organisms classified as a unit.
Each level of this hierarchy is called the taxonomic category or ranks.
Species is the lowest level in taxonomy and it is a group of organisms with most similar characters present in the Earth. There are also several sub-species to this category.

Therefore, the correct answer for this question is option (C).

Note:
> Taxonomic hierarchy is the process which consists of arranging various organisms into successive levels of biological classifications in a decreasing or an increasing order.
In this system of classification kingdom comes first and species come last.
> Each rank is classified further into several general categories according to their traits.
> Each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits from common ancestors.
> The rank of any species and the description of its genus is basic; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.
 > When a formal name is given only then is usually a rank assigned by the taxon. The basic rank consists of species and genus. The genus name is a part of the species name and the species name is assigned to a genus.
