Step by step
Solved in 2 steps
- 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. Separation of homologous chromosome 2. Four haploid daughter cells are formed.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.Oogenesis is the process of female gamete (ovum or egg) production in animals. Spermatogenesis is the process of male gamete (sperm) production in animals. Although both processes produce gamete(s), there are distinct similarities and differences between the two. Compare and contrast oogenesis to spermatogenesis by drawing a diagram showing the two processes. In your hand-drawn diagrams, be sure to include when the processes of mitosis, meiosis I and meiosis II are occurring identify each germ cell structure and its ploidy highlight 4 differences between the two processes
- What are the major differences between mitosis and meiosis? Explain this both in terms of the different steps of each event and with regards to the final products of each event. Remember to mention the events which are unique to meiosis and why they are significant.A cat germ cell has a haploid number of 19 chromosomes.Complete the following table by stating the number of cells, the number of chromatids, and the number of chromosomes at the end of each of the following stages of meiosis and mitosis. (Please note this is an emply chart, I'm unsure why it got declined last time because it is not graded) Meiosis Meiosis Mitosis Prophase I Telophase I Telophase Number of cells Number of Chromatids Number of ChromosomesFor 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 (meiosis I and meiosis II for prophase, metaphase, anaphase, telophase, and cytokinesis)
- a. What type of cell division mitosis, meiosis I or meiosis II is shown in this figure? b. What is the diploid number of this organism? c. Provide labels for (i) and (ii)1)Discusses why Meiosis I is referred to as reduction division and why Meiosis II is essentially like Mitosis. 2)Discusses where problems are likely to occur in Meiosis and what these problems could lead to.Meiosis In this worksheet, you will review the steps of meiosis and view video simulations of this type of cell division. You will also view an onion root tip and calculate the percentage of cells at each of the stages of cell division. Stages of Meiosis Visit http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/main.html for an additional review of Meiosis Part 1: Reproduction 1. Give an example of asexual reproduction. 2. What is a clone? 3. What is the difference between haploid and diploid? Part 2: Chromosomes in a Diploid Cell 4. What is the diploid chromosome number for humans? 5. Egg and sperm cells are [haploid / diploid] Part 3: Meiosis 1 and Meiosis 2 6. Name the stage of meiosis 1 where each of the following occurs: ● Homologous chromosomes pair and form synapses. . Bivalents align at metaphase plate ● Two complete daughter cells form Nuclear membrane disappears. Nuclear membrane reforms. Chromosomes move to separate pole ● ●
- Distinguish between the following terms: somatic cell and gamete; autosome and sex chromosomes; haploid and diploid. Describe the events that characterize each phase of meiosis. Describe three events that occur during meiosis I but not mitosis. Name and explain the three events that contribute to genetic variation in sexually reproducing organisms.Which one of the following entries most accurately describes the stage at which oogenesis is reinitiated? Oogenesis is reinitiated at prophase of mitosis Oogenesis is reinitiated at prophase I of meiosis Oogenesis is reinitiated at prophase II of meiosis Oogenesis is not reinitiated.meiosis is often termed as a reduction division. what is reduced and when is it reduced?
