Species is the lowest taxonomic category. Class is a category made of one or more related orders possessing similar correlated characters. Family is composed of one to many related genera. Division comprises of several related classes.

Less General than Genus

In the Linnaean system of classification, organisms are grouped into a hierarchy of categories based on their similarity in characteristics. The most general category is the kingdom, followed by phylum, class, order, family, genus, and species. Each category becomes more specific and less general than the previous one.

The question asks which of the following categories is less general than genus. The answer is:

a) Species

Explanation

Species is the least general category in the Linnaean system of classification. It refers to a group of organisms that share similar characteristics and can interbreed to produce fertile offspring. Species is less general than genus because it is a more specific category that includes only organisms that are closely related.

Other Categories

The other categories listed in the question are more general than genus:

- Division: This is not a category in the Linnaean system of classification. It is sometimes used as an alternative to phylum in some groups of organisms, such as plants.
- Class: This is a category that includes organisms that share similar characteristics, but are less closely related than those in the same order or family.
- Family: This is a category that includes organisms that are closely related and share many characteristics, but are less closely related than those in the same genus.

Conclusion

In summary, species is less general than genus in the Linnaean system of classification. It is the least general category and includes only organisms that are closely related and can interbreed to produce fertile offspring.
