Family Classification in Taxonomy — NEET Biology
✅ Asked in NEET 2019The common characteristics between tomato and potato will be maximum at the level of:-
The common characteristics between tomato and potato will be maximum at the level of:-
Answer & NCERT explanation
Correct answer: D — Family
Tomato and potato both belong to family Solanaceae, so they share maximum common characteristics at family level. As we go higher in hierarchy (Order, Class), organisms become more diverse. At genus level, they belong to different genera (Solanum vs Lycopersicon), so family level shows maximum similarity.

The next category, Family, has a group of related genera with still less number of similarities as compared to genus and species. Families are characterised on the basis of both vegetative and reproductive features of plant species. Among plants for example, three different genera Solanum, Petunia and Datura are placed in the family Solanaceae. Among animals for example, genus Panthera, comprising lion, tiger, leopard is put along with genus, Felis (cats) in the family Felidae. Similarly, if you observe the features of a cat and a dog, you will find some similarities and some differences as well. They are separated into two different families – Felidae and Canidae, respectively.
The Family level in biological classification groups related genera together based on shared vegetative and reproductive features. NTA tests this by asking students to identify which genera belong to which family (e.g., Solanum, Petunia, Datura in Solanaceae). Students often confuse Family with Genus or Species, forgetting that Family contains multiple genera with fewer similarities than species within a genus. Key takeaway: Remember that taxonomic hierarchy goes Species → Genus → Family, where each level has progressively broader characteristics. Solanum species (potato, tomato) should always be associated with Solanaceae family—this specific link appears frequently in NEET questions.
