Part1. Option 3rd; Somatic cells such as liver cells cannot undergo meiosis cell division. Mitotic cells are required to be diploid in number of chromosomes. Sperm cells and germ cells are undergo fusion with other reproductive cells, thus they get diploid chromosomes after fusion. So body’s maximum cells like somatic cells undergo mitosis rather than meiosis. Part2. The S phase includes the duplication of each chromosome. All DNA has duplicated in this section by multiple sites of duplication. Part3. Maternal and parental chromosomes are separated in Anaphase I of meiosis cell division. These are non-identical sister chromatids. Part4. The Anaphase II is responsible for the separation of sister chromatids to form chromosomes. Sister chromatids are chromosomes of either maternal or paternal. Part5. During Prophase I homologous chromosomes physically pair up. This phase includes paring up of chromosomes and homologous recombination. Solution Part1. Option 3rd; Somatic cells such as liver cells cannot undergo meiosis cell division.
