Briefly explain what 2n=12 means in terms of mitosis and meiosis.
Please compare the processes of Meiosis 1 and Meiosis 2 for a cell that has a diploid number of 6. Please describe each stage, and how they are different in Meiosis 1 and Meiosis 2. you will also need to highlight where genetic variation can be increased throughout the process.
Picture name - Tradescantia spathacea meiotic cell. HPO (400x)Shown below are photomicrographs of Rhoeo tradescantia cells undergoing meiosis. Answer the following question for each of the photomicrographs: Identify the cytogenetic abnormality observed (ex. ring, chain, laggard, bridge). Identify the meiotic stage in which these aberrations are observed (as shown in the photomicrograph). Explain how these aberrations are formed and relate to the possible causal mutation(s). Will this result to sterile and/or fertile gametes? Explain.
Identify the stages of meiosis described by the following meiotic events/conditions/terms. Write prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, or telophase II. In case the events are found in both stages, write the stages both. 1. Formation of chiasma 2. Each chromatid is considered as full-fledged chromosome. 3. Chromosomes begin to pair off. 4. Spindle microtubules start to attach to the centromere. 5. Tetrads are aligned at the middle of the cell. 6. The sister chromatids separate. 7. Produce 2 haploid daughter cells. 8. The chromosomes line up at the middle of the cell. 9. The sister chromatids move together to the opposite poles. 10. The chromatids reach the poles. 11. The chromosomes in each daughter cell are still duplicated.12. Spindle microtubules attach in the centromere of each haploid daughter cell. 13.
Metaphase of mitosis differs from metaphase of meiosis I because homologous chromosomes do not interact in meiosis I. homologous chromosomes do not interact in mitosis. metaphase does not occur in meiosis I. sister chromatids are not present in meiosis I.
For the animal cell sketch the process of meiosis. Needs to illustrate the process from start to finish, and highlight the chromosomal condition of cells through the meiotic phase Include the labels of: Interphase Mitotic (must includemeiosis I and meiosis II for prophase, metaphase, anaphase, telophase, and cytokinesis)
Match the phases of meiosis with their descriptions. Question 6 options: chromatids of chromosomes are pulled apart and move toward the cell sides nuclear membrane disappears and tetrads form chromosomes align along the middle of the cell tetrads align along the middle of the cell chromosomes from tetrads reach the sides of the cells and the nulcear membrane reforms chromatids of chromosomes reach the cell sides and the nuclear membrane reforms; cytokinesis occurs near the end chromosomes reside in the cell's center and the nuclear membrane disappears chromosomes of tetrads separate and move toward the cell sides 1. prophase 1 2. metaphase 1 3. anaphase 1 4. telophase 1 5. prophase 2 6. metaphase 2 7. anaphase 2 8. telophase 2
1. Compare and contrast mitosis and meiosis by placing a check in the appropriate space if the feature applies. Features Mitosis Meiosis I Meiosis II Preceded by replication of DNA. Involves a reduction division. Involves synapsis (pairing of homologous chromosomes). Chiasmata formed (crossing over). At metaphase the centromeres lie on the equatorial plane. At metaphase the centromeres of homologous chromosomes lie on either side of the equatorial plane. At anaphase chromatids separate and move to opposite poles. At anaphase homologous chromosomes separate and move to opposite poles. Number of daughter nuclei generated from parent nucleus. (provide the number) Daughter nuclei have the same number (2n) of chromosomes as parent nucleus. Daughter nuclei have 1/2 (n) the number of chromosomes. Daughter nuclei have the same chromosome as the parent nuclei.…
Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes? Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is introduced in meiosis, but not in mitosis Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is reduced in meiosis, but not in mitosis. Metaphase and telophase portions of meiosis and mitosis are the same. Meiosis and mitosis are also the same, except for the number of chromosomes. Anaphase I and anaphase are different. Prophase and telophase portions of meiosis and mitosis are the same. Meiosis II and mitosis are also the same and have the same number of chromosomes. Anaphase I and anaphase are different.
