NEET Zoology Syllabus (Latest) PDF– Chapter-wise Topics, Weightage & Expert Tips

What Is in the NEET Zoology Syllabus 2027?

NMC lists Biology as one subject with 10 units, so zoology is the animal-side share of those units. The grouping below is the one used across our Biology, Zoology and Botany pages, so a topic is never counted in two places.

Has anything changed for 2027? Not officially. The 2026 syllabus was unchanged from 2025, and the live status is tracked on the main NEET syllabus 2027 page. The paper layout is in the NEET exam pattern guide. Official sources: nmc.org.in and neet.nta.nic.in.

Class 11 Zoology Syllabus for NEET 2027: Animal Kingdom, Animal Tissues and Human Physiology

Class 11 supplies 8 of the 12 core zoology chapters. Topics are paraphrased from the official NMC unit text; the “Revise with” lines are study cues, not syllabus items.

Class 12 Zoology Syllabus for NEET 2027: Reproduction, Evolution and Human Health

Human Reproduction (Unit 6)

• Male and female reproductive systems; microscopic anatomy of testis and ovary
• Gametogenesis: spermatogenesis and oogenesis; menstrual cycle
• Fertilisation, embryo development up to blastocyst, implantation
• Pregnancy and placenta, parturition and lactation (elementary idea)
• Revise with: hormone levels across the menstrual cycle; stage-wise gametogenesis diagrams

Reproductive Health (Unit 6)

• Need for reproductive health; prevention of sexually transmitted diseases
• Birth control: need, methods, contraception; medical termination of pregnancy
• Amniocentesis; infertility and assisted reproductive technologies: IVF, ZIFT, GIFT (general awareness)
• Revise with: a contraceptive methods table grouped by type

Evolution (Unit 7)

• Origin of life; evidence for evolution from palaeontology, comparative anatomy, embryology and molecular biology
• Darwin’s contribution and the modern synthetic theory
• Mechanisms: mutation and recombination, natural selection and its types, gene flow, genetic drift
• Hardy–Weinberg principle; adaptive radiation; human evolution
• Revise with: the Hardy–Weinberg equations and a human-evolution timeline table

Human Health and Disease (Unit 8)

• Pathogens and parasites causing malaria, filariasis, ascariasis, typhoid, pneumonia, common cold, amoebiasis, ringworm, dengue and chikungunya
• Basic immunology and vaccines; cancer; HIV and AIDS
• Revise with: a disease–pathogen–vector–symptom table

Microbes in human welfare, the second part of Unit 8, is covered on the NEET Botany syllabus page.

Zoology Side of the Shared Units: Cell, Genetics, Biotechnology and Ecology

Four units are counted on both sides, so their full topic text lives on the Biology page. Use this table to see which parts tend to be animal- or human-focused, then study them from the NEET Biology syllabus 2027.

Frog in the NEET Zoology Syllabus: What to Study

Study the frog as a brief account of its body and five organ systems. The cockroach was replaced by the frog; the full change summary is in the Biology page section on the cockroach and frog.

The official unit line reads “insect (Frog)”, but the frog is an amphibian. Use the frog section of the Structural Organisation in Animals chapter, and skip the cockroach.

Which Zoology Topics Are Removed from the NEET Zoology Syllabus 2027?

No zoology unit was dropped, but several chapters and topics are no longer listed. 

Newly emphasised on the zoology side: the frog, and dengue and chikungunya in Unit 8. Because sources occasionally differ on small points, confirm against the official syllabus PDF.

NEET Zoology Chapters Mapped to NCERT

Zoology has 12 core NCERT chapters, 8 in Class 11 and 4 in Class 12. Chapter titles differ slightly between NCERT editions, so follow the unit text rather than the title.

Shared chapters (Biomolecules, Cell Cycle and Cell Division, Principles of Inheritance and Variation, Molecular Basis of Inheritance, the two Biotechnology chapters, and the three Ecology chapters) are listed in the Biology page NCERT mapping. Keep the NCERT books and NCERT Solutions for Class 11 and Class 12 open as you work.

NEET Zoology Chapter-Wise Importance: Which Chapters Matter Most?

Evolution and Human Reproduction stood out among zoology chapters in the 2026 analyses. Use this to order your revision, never to skip a chapter. The wider Biology picture is in the Biology chapter-wise weightage section.

Counts differ slightly between analyses because the papers were set in several codes, and they reflect 2026 only, not a fixed rule. For the other chapters, group your revision by how they are asked:

Read the full NEET 2026 paper analysis, then practise with chapter-wise NEET PYQs with solutions and NEET important questions.

How to Study NEET Zoology for NEET 2027

Read each zoology NCERT chapter line by line, redraw every diagram, and finish with chapter-wise previous year questions. Zoology rewards precise recall of NCERT lines, tables, and labelled diagrams, so accuracy matters more than speed.

Fit this into the NEET 2027 syllabus plan and the wider Biology study plan. Revise with NEET revision notes, revision videos, mind maps, and NEET previous year papers. For an expert-led daily structure, see eSaral NEET courses and the NEET test series.
