Unit-I Reproduction 
 
Chapter-1: Sexual Reproduction in Flowering Plants Flower structure; development of male and female 
gametophytes; pollination - types, agencies and examples; out breeding devices; pollen-pistil interaction; double 
fertilization; post fertilization events - development of endosperm and embryo, development of seed and formation 
of fruit; special modes- apomixis, parthenocarpy, polyembryony; Significance of seed dispersal and fruit formation. 
 
Chapter-2: Human Reproduction Male and female reproductive systems; microscopic anatomy of testis and ovary; 
gametogenesis -spermatogenesis and oogenesis; menstrual cycle; fertilisation, embryo development upto blastocyst 
formation, implantation; pregnancy and placenta formation (elementary idea); parturition (elementary idea); lactation 
(elementary idea). 
 
Chapter-3: Reproductive Health Need for reproductive health and prevention of Sexually Transmitted Diseases 
(STDs); birth control - need and methods, contraception and medical termination of pregnancy (MTP); 
amniocentesis; infertility and assisted reproductive technologies - IVF, ZIFT, GIFT (elementary idea for general 
awareness). 
 
Unit-II Genetics and Evolution 
 
Chapter-4: Principles of Inheritance and Variation Heredity and variation: Mendelian inheritance; deviations from 
Mendelism – incomplete dominance, co-dominance, multiple alleles and inheritance of blood groups, pleiotropy; 
elementary idea of polygenic inheritance; chromosome theory of inheritance; chromosomes and genes; Sex 
determination - in humans, birds and honey bee; linkage and crossing over; sex linked inheritance - haemophilia, 
colour blindness; Mendelian disorders in humans - thalassemia; chromosomal disorders in humans; Down's 
syndrome, Turner's and Klinefelter's syndromes. 
 
Chapter-5: Molecular Basis of Inheritance Search for genetic material and DNA as genetic material; Structure of 
DNA and RNA; DNA packaging; DNA replication; Central Dogma; transcription, genetic code, translation; gene 
expression and regulation - lac operon; Genome, Human and rice genome projects; DNA fingerprinting. 
 
Chapter-6: Evolution Origin of life; biological evolution and evidences for biological evolution (paleontology, 
comparative anatomy, embryology and molecular evidences); Darwin's contribution, modern synthetic theory of 
evolution; mechanism of evolution - variation (mutation and recombination) and natural selection with examples, 
types of natural selection; Gene flow and genetic drift; Hardy- Weinberg's principle; adaptive radiation; human 
evolution. 
 
Unit-III: Biology and Human Welfare 
 
Chapter-7: Human Health and Disease Pathogens; parasites causing human diseases (malaria, dengue, chikungunya, 
filariasis, ascariasis, typhoid, pneumonia, common cold, amoebiasis, ring worm) and their control; Basic concepts of 
immunology - vaccines; cancer, HIV and AIDS; Adolescence - drug and alcohol abuse. 
  
Chapter-8: Microbes in Human Welfare 
Microbes in food processing, industrial production, sewage treatment, energy generation and microbes as bio-control 
agents and bio-fertilizers. Antibiotics; production and judicioususe. 
 
Unit-IV Biotechnology and its Applications 
 
Chapter-9: Biotechnology : Principles and Processes Genetic Engineering (Recombinant DNA Technology). 
 
Chapter-10: Biotechnology and its Applications Application of biotechnology in health and agriculture: Human 
insulin and vaccine production, stem cell technology, gene therapy; genetically modified organisms - Bt crops; 
transgenic animals; biosafety issues, biopiracy and patents.

population attributes - growth, birth rate and death rate, age distribution. (Topics excluded: Organism and its 
Environment, Major Aboitic Factors, Responses to Abioitic Factors, Adaptations) 
 
Chapter-12: Ecosystem Ecosystems: Patterns, components; productivity and decomposition; energy flow; pyramids 
of number, biomass, energy (Topics excluded: Ecological Succession and Nutrient Cycles).

biodiversity conservation; hotspots, endangered organisms, extinction, Red Data Book, Sacred Groves, biosphere 
reserves, national parks, wildlife, sanctuaries and Ramsar sites.
