    GIVE AN ACCOUNT OF THE ROLES OF GENETIC MUTATIONS AND MEIOSIS IN GENERATING GENETIC DIVERSITY (20) Marking Scheme Synopsis‚ Clarity‚ English Language‚ sequence of events (3) Introduction (1)‚ Scientific content (15)‚ Conclusion (1). Introduction: Genetic Diversity: Every individual has a unique genotype. This is equal to the combination of alleles of all its genes. The greater the number of genotypes in a population‚ the greater the genetic diversity. Genetic mutations produce new alleles

    Mitosis is a process of cell duplication‚ or reproduction‚ where one during this process gives growth to two identical daughter cells; however‚ there is no crossing over. Mitosis is asexual and has 1 division of the nucleus in cytokinesis (Simon‚ Reece‚ & Dickey‚ 2010). Meiosis is the splitting up of germ cells‚ with each possessing half the number of & Dickey‚ 2010). Meiosis is sexual and has 2 nuclear and cytoplasmic divisions. However‚ one must remember they both are preceded by Interphase

    Describe the normal process of cell division (mitosis)‚ and explain how this process is affected in the abnormal growth of tumours Cell division is important as it allows cells to reproduce also they divide so that organs can grow and be repaired. “In the form of cell division called Mitosis‚ one cell divides into two daughter cells‚ each of them then complete but smaller than the original cell.” [1] The cell cycle is a seven stage process by which a cell duplicates itself and divides in two.

    cell reproduction‚ mitosis and meiosis and‚ include the different stages required in order for the reproduction to take place. Mitosis Mitosis is a process by which a cell divides to form two daughter cells and produces an almost carbon copy of the parent cell. The daughter cells will consist of the same number and type of chromosomes as the parent cell and will be identical to each other. Although cell division is the defining characteristic of mitosis‚ a number of events
