RPSC Agriculture Research Officer (Entomology) - 2024 (Q.90)

MCQ (Single Correct) +1 −0.33

A population or group of individuals of identical genotype is known as -

आनुवांशिक रूप से समान जीवों के समूह या जनसंख्या को कहते हैं -

Taxon टेक्सॉन Sibling species सिबलिंग जातियाँ Biotype बायोटाइप Subspecies उपजातियाँ

biotype is defined as a group of individuals within a species possessing an identical genetic constitution or physiological specialization.
In entomology, biotypes frequently arise through selection pressure from resistant host plants (e.g., Nilaparvata lugens biotypes overcoming specific rice resistance genes).
taxon is a formal taxonomic unit of any hierarchical rank (e.g., family, genus, or species).
Sibling species are reproductively isolated distinct species that are morphologically indistinguishable, while subspecies are geographically separated lineages.

Hence, the correct option is (C).

बायोटाइप आनुवंशिक रूप से समान जीवों या एक ही आनुवंशिक संरचना वाले जीवों की जनसंख्या को कहा जाता है।
कीट विज्ञान में बायोटाइप अक्सर प्रतिरोधी किस्मों के चयन दबाव से विकसित होते हैं (जैसे भूरे फुदके के विभिन्न बायोटाइप)।
टेक्सॉन किसी भी स्तर की एक औपचारिक वर्गीकरण इकाई (जैसे कुल, वंश, या जाति) होती है।
सिबलिंग जातियाँ शारीरिक रूप से समान दिखने वाली परंतु जननात्मक रूप से पृथक स्वतंत्र जातियाँ होती हैं।

अतः सही विकल्प (C) है।
