Std. - XII Biology Section II – Zoology: Unit 1: Genetics and Evolution Chapter 10 - Origin and the Evolution of Life: Origin of Life: Early Earth, Spontaneous, assembly of organic compounds, Evolution: Darwin‟s contribution, Modern Synthetic Theory of evolution, Biological Evidences, Mechanism of evolution; Gene flow and genetic drift;Hardy-Weinberg principle; Adaptive radiation. Origin and Evolution of Human being. Chapter 11 - Chromosomal Basis of Inheritance: The Chromosomal Theory. Chromosomes. Linkage and Crossing Over. Sex-linked Inheritance (Haemophilia and colour blindness). Sex Determination in Human being, birds, honey bee.Mendelian disorders in humans- Thalassemia. Chromosomal disorders in human: Down’s syndrome, Turner’s syndrome and Klinfelter’s syndrome. Unit 2: Biotechnology and its application Chapter 12- Genetic Engineering and Genomics: DNA Finger Printing. Genomics and Human Genome Project. Biotechnological Applications in Health: Human insulin and vaccine production, Gene Therapy. Transgenic animals. Unit 3: Biology and Human Welfare Chapter 13- Human Health and Diseases: Concepts of Immunology: Immunity Types, Vaccines, Structure of Antibody, Antigen-Antibody Complex, Antigens on blood cells. Pathogens and Parasites (Amoebiasis, Malaria, Filariasis, Ascariasis, Typhoid, Pneumonia, Common cold and ring worm). Adolescence, drug and alcohol abuse. Cancer and AIDS.

Dissect the given flower and display different whorls. Dissect anther and ovary to show number of chambers. 2. Study pollen germination on a slide. 3. Collect and study soil from at least two different sites and study them for texture, moisture content, pH and water holding capacity of soil. Correlate with the kinds of plants found in them. 4. Study of plant population density and frequency by quadrate method. 5. Prepare a temporary mount of onion root tip to study mitosis. 6.

Collect water from two different water bodies around you and study them for pH, clarity and presence of any living organisms.. 10. To test the presence of urea and sugar in urine. 11To test the presence of albumin and bile salts in urine. Study/observation of the following (Spotting): 1 Study of flowers adapted to pollination by different agencies (wind, insect) 2 Study of pollen germination on stigma through a permanent slide. 3 To Study Mendelian inheritance using seeds of different colour/size of any plant. 4 Exercise on controlled pollination - Emasculation, tagging and bagging 5 Study meiosis in onion bud cell or grass hopper testis through permanent slide. 6 Study plants found in xerophytic and aquatic conditions with respect to their morphological adaptations.(Two plants each) 7 Study and identify stages of gamete development, T.S. of testis and T.S. ovary through permanent slides (from any mammal). 8.
