In the scientific name Felis domestica, what does the term Felis represent?

  1. Genus

  2. Species

  3. Family

  4. Kingdom

The correct answer is: Genus

The term "Felis" in the scientific name Felis domestica represents the genus of the organism. In biological classification, the genus is a rank that is one level above species and it encompasses a group of closely related species that share common characteristics. In this case, "Felis" includes domestic cats and other feline species, attributing to them a common ancestry and certain shared features. This hierarchical classification helps biologists and researchers systematically categorize and study living organisms based on their evolutionary relationships. Understanding that "Felis" is the genus helps clarify how scientists categorize different species within this group, highlighting the importance of genus in the broader context of taxonomy.
