Unit I: Reproduction 
Reproduction in organisms: Reproduction, a characteristic feature of all organisms for continuation of species; 
Modes of reproduction – Asexual and sexual; Asexual reproduction; Modes- Binary fission, sporulation, 
budding, gemmule, fragmentation; vegetative propagation in plants. 
Sexual reproduction in flowering plants: Flower structure; Development of male and female 
gametophytes; Pollination –types, agencies and examples; Outbreedings 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 
and fruit formation. 
Human Reproduction: Male and female reproductive systems; Microscopic anatomy of testis and ovary; 
Gametogenesis- spermatogenesis & oogenesis; Menstrual cycle; Fertilisation, embryo development upto 
blastocyst formation, implantation; Pregnancy and placenta formation (Elementary idea); Parturition 
(Elementary idea); Lactation (Elementary idea). 
 
Reproductive health: Need for reproductive health and prevention of sexually transmitted diseases (STD); 
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 
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, honey bee; Linkage and crossing 
over; Sex linked inheritance- Haemophilia, Colour blindness; Mendelian disorders in humans – Thalassemia; 
Chromosomal disorders in humans; D o w n ’ s syndrome, T u r ner ’ s and K l i ne f el t e r ’ s syndromes. 
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 and human genome project; DNA finger printing. 
Evolution: Origin of life; Biological evolution and evidences for biological evolution (Paleontological, comparative 
anatomy, embryology and molecular evidence); D a r w i n ’ 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 dirft; Hardy- W e i n b e r g ’ s principle;Adaptive Radiation; Human evolution. 
 
Unit III: Biology and Human Welfare 
Health and Disease: Pathogens; parasites causing human diseases (Malaria, Filariasis, Ascariasis, Typhoid, 
Pneumonia, common cold, amoebiasis, ring worm); Basic concepts of immunology –vaccines; Cancer, HIV and 
AIDs; Adolescence, drug and alcohol abuse. 
Improvement in food production: Plant breeding, tissue culture, single cell protein, Biofortification; Apiculture and 
Animal husbandry. 
Microbes in human welfare: In household food processing, industrial production, sewage treatment, energy 
generation and as biocontrol agents and biofertilizers. 
 
 
Note:  
There will be one Question Paper which will have 50 questions out of which 40 questions need to be 
attempted.
