In biological classification, a collection of genera is referred to as what?

In biological classification, a collection of genera is referred to as a family. The classification system, known as taxonomy, organizes living organisms into a hierarchy of categories.

The hierarchy starts with the broadest category and becomes more specific as it progresses. In this system, the order comprises multiple families, which in turn encompass multiple genera. Thus, a family is a more specific level in which genera that share common characteristics are grouped together, making it an essential part of the classification structure.

When considering the other categories: species represents the most specific level, referring to individual organisms that can interbreed, while class encompasses broader groupings of families. Lastly, order groups together families sharing larger-scale similarities but is broader than the family level. Therefore, family is the correct answer as it directly corresponds to a collection of genera in the hierarchical structure of biological classification.
