4. सबसे महत्वपूर्ण Concept
Rule 1
जैसे-जैसे ऊपर जाते हैं
Species → Kingdom
✔ Common characters कम होते जाते हैं
✔ Organisms की संख्या बढ़ती जाती है
Rule 2
जैसे-जैसे नीचे आते हैं
Kingdom → Species
✔ Similarity बढ़ती जाती है
✔ Common characters बढ़ते जाते हैं
✔ Organisms की संख्या घटती जाती है
NEET Trick
| Category | Similarity |
|---|---|
| Species | Maximum |
| Kingdom | Minimum |
याद रखो:
Species = Most Similar
Kingdom = Least Similar
5. Species (सबसे महत्वपूर्ण)
Definition
ऐसे जीवों का समूह जो
✔ आपस में प्रजनन कर सकें
✔ Fertile offspring उत्पन्न कर सकें
✔ Fundamental similarities रखते हों
NEET Favourite Question
Basic Unit of Classification?
✅ Species
6. Taxonomic Categories का Logic
Many Species = One Genus
Many Genera = One Family
Many Families = One Order
Many Orders = One Class
Many Classes = One Phylum
Many Phyla = One Kingdom
Short Trick
S → G → F → O → C → P → K
