Key Zoology Chapters for NEET UG 2025
- Human Physiology
Human Physiology consistently ranks as the most significant topic in the NEET examination. Subjects such as the digestive system, respiration, circulation, excretion, neural control, and chemical coordination are frequently tested. Further, candidates should ensure a comprehensive understanding of these concepts and engage in practice with diagram-based questions. - Genetics and Evolution
This chapter is recognized as one of the more complex yet rewarding sections. Key topics include Mendelian genetics, the molecular basis of inheritance, chromosomal disorders, and Darwin’s theory of evolution, all of which are commonly featured in the examination. - Animal Kingdom
As a foundational topic, the Animal Kingdom encompasses classifications, characteristics, and examples of various phyla. A clear understanding of the distinctions between chordates and non-chordates is essential for tackling application-based questions. - Human Reproduction and Reproductive Health
This unit addresses reproductive structures, gametogenesis, fertilization, pregnancy, and contraceptive methods. Given the prevalence of direct questions on this subject, students should concentrate on diagrams and flowcharts to enhance retention. - Biotechnology and its Applications
An increasingly important area, this chapter covers genetic engineering, recombinant DNA technology, biotechnological applications in health and agriculture, as well as ethical considerations. The NEET examination often includes conceptual and application-based questions from this field. - Ecology and Environment
This section addresses vital subjects such as environmental challenges, ecosystem dynamics, energy transfer, biodiversity preservation, and species interactions. Given the growing focus on environmental issues, questions from this chapter frequently appear in examinations.
