Introduction Meiosis is sexual reproduction, a process that occurs only in the sex cell rather than the somatic cells of an animal. This process includes converting one diploid cell into four haploid cells through various phases the cell undergoes, resulting in dividing the chromosomes among these four cells. The first phases of meiosis (meiosis 1) include Prophase 1, Metaphase 1, Anaphase 1, and Telophase 1 respectively. Prophase 1 is the stage of meiosis cycle where the homologous chromosomes couple up and form tetrads. The formation of tetrads plays an important role in meiosis. Crossing over occurs in prophase 1 because the paired tetrads swab segments of the chromosomes. Metaphase 1 is the phase in meiosis where the paired tetrads line up together on the equator of the cell. It is important to note that homologous airs line up in metaphase 1 not chromosomes. The centrosomes begin to form microtubule …show more content…
The Sordaria fimicola's life cycle begins when the Sordaria is a single cell (unicellular) organism. The single cell is spread from a multicellular Sordaria fimicola. As this lab was prepared beforehand it is necessary to know that we must allow around seven days to see fully matured cells. As the cells undergo mitosis they continue to duplicate making more and more cells, the Sordaria fimicola forms a perithecium, which provides great support for the growth of the Sordaria (Saleem, 2001). The perithecium is the non-sexual part of the fungus. It holds the asci, which is made up of multiple ascospores. Therefore since the diploid cells of the Sordaria fimicola only undergo meiosis because only diploid cells have homologous pairs of chromosomes. This proves the fact that haploid cells cannot undergo meiosis since haploid cells lack homologous pairs of chromosomes, therefore are able to undergo
