Unformatted text preview: Define mitosis, meiosis, fertilization. Explain how fertilization and meiosis relate to the formation of haploid and diploid cells. Identify which cell can undergo mitosis to produce a multicellular organism, and explain how the life cycles of plants, animals and fungi differ in this regard. Explain how you can generate four haploid cells from one diploid cell. Define homologous chromosome, sister chromatid, maternal and paternal chromosomes, tetrad. Draw and explain how chromosomes are sorted during meiosis. Identify the stage when homologous chromosomes are separated. Identify the stage when sister chromatids are separated. Explain at what stage in meiosis (a) recombination (crossing over) and (b) independent assortment occur. Explain the adaptive value of recombination....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
