Vernalisation — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Vernalisation.

Scenario-based application of obligate vs. facultative vernalisation.

high

NEET increasingly favors application-based questions. A scenario describing a plant's behavior under different temperature regimes (e.g., 'Plant X flowers only after cold, Plant Y flowers faster after cold but eventually without it') and asking to identify their vernalisation type (obligate/facultative) would test conceptual understanding and application. This avoids simple recall and encourages deeper thought about the implications of each type.

Molecular basis of vernalisation (e.g., FLC gene function).

medium

While NEET generally avoids highly detailed molecular biology, the concept of *FLC* as a repressor gene whose expression is silenced by cold is a fundamental breakthrough in vernalisation research. A simplified question about a 'flowering repressor gene' being downregulated by cold, without delving into complex epigenetic mechanisms, could be introduced to test awareness of modern biological understanding. This would be a step up from basic physiological questions.

Integrated question combining vernalisation with other growth regulators or environmental factors.

high

NEET often tests integrated knowledge. A question might combine vernalisation with the role of gibberellins and photoperiodism. For example, 'A long-day biennial plant requires vernalisation. If grown under short-day conditions without cold, and then treated with gibberellins, what is the most likely outcome?' Such questions assess the student's ability to synthesize information from related topics within Plant Growth and Development.
