Biological Science (BIOS)
2 units: Reproduction, Genetics and Evolution.
Detailed syllabus
Unit 1: Reproduction (33 hours, 15 marks)
Sexual reproduction in flowering plants (gametophytes, pollination, outbreeding devices, double fertilisation, endosperm, embryo and seed, apomixis, parthenocarpy, polyembryony); human reproduction (reproductive systems, gametogenesis, menstrual cycle, fertilisation, implantation, pregnancy, parturition, lactation); reproductive health (STDs, contraception, MTP, amniocentesis, infertility and ART: IVF, ZIFT, GIFT).
Unit 2: Genetics and Evolution (57 hours, 20 marks)
Principles of inheritance and variation (Mendelian inheritance, incomplete and co-dominance, multiple alleles and blood groups, pleiotropy, polygenic inheritance, chromosome theory, sex determination, linkage, sex-linked inheritance, Mendelian and chromosomal disorders, pedigree analysis); molecular basis of inheritance (DNA as genetic material, DNA and RNA structure, replication, central dogma, transcription, genetic code, translation, lac operon, genome projects, DNA fingerprinting); evolution (origin of life, evidences, Darwin and the modern synthetic theory, natural selection, gene flow, genetic drift, Hardy-Weinberg principle, adaptive radiation, human evolution).
