Question

A taxonomic group of related genera is known as _____
A. Species
B. Order
C. Family
D. Class

Answer 1

Hint: In classification, the organisms that closely resemble one another are placed in a group, the groups which have similarities are combined together into larger groups and those into still larger ones. The taxonomic categories are the various levels or groups in the classification system

Complete answer: A group of individuals that constitute a group of actually or potentially inbreeding populations and are reproductively isolated from other such groups is known as species. Species occupy a key position in the classification as it is the lowest category. The organisms in a species that show certain distinct features of their own form a subspecies or subgroups or varieties.
Genus is a group of species alike in the broad features of their organization but different in details. The species in a genus share a common ancestry. Correlated characters are the common features that various species have in common for qualifying for inclusion in a genus.
 A family is a group of related genera. The genus Felis of cats and the genus Panthera of lion, tiger and leopard are placed in the family felidae. All these animals have retractile claws.
An order is a group of related families. The family Felidae of cats and the family Canidae of dogs are assigned to order Carnivora. Both dogs and cats have canine teeth and they are flesh-eaters.
A class is a group of related orders. The order Rodentia of rats, Lagomorpha of rabbits and Carnivora of cats and dogs, are placed in the class Mammalia. They all have hair and milk glands.
So, the correct answer is “Option C”.

Note: There are seven major taxonomic categories. The most inclusive category is Kingdom. Other major categories in descending order are phylum, class, order, family, genus and species. Every species for classification is traced to these seven basic categories.
