NEET Biology: High Weightage Topics

If you have less time, focus on these "Gold Mine" chapters. They account for nearly 60% of the paper.

🧬 Genetics & Evolution (15-18 Questions)

• Mendelian Disorders: Hemophilia, Color Blindness, Sickle Cell Anemia (Memorize the pedigrees!).
• Molecular Basis: Lac Operon, DNA Replication package, Human Genome Project goals.

🌱 Ecology (10-12 Questions)

• Biodiversity: Examples of In-situ vs Ex-situ conservation.
• Population: Verify the Age Pyramid diagrams and Growth Curves (J-shaped vs S-shaped).

🦠 Human Physiology (12-15 Questions)

• Chemical Coordination: Hormones of Pituitary and Thyroid (and their disorders).
• Neural Control: Mechanism of generation of Nerve Impulse and the structure of the Ear/Eye.

🔬 Biotech (8-10 Questions)

• Principals: Restriction Enzymes (EcoRI naming), PCR steps (Denaturation, Annealing, Extension).
• Applications: Bt Cotton mechanism, RNA interference, Insulin production (Eli Lilly).

🌿 Plant Physiology (8-10 Questions)
