Summary Introduction
Introduction:
The cell division is of 2 types, mitosis and meiosis. The mitosis is the process of the cell division, which occur in all the somatic cells present in the body of the multicellular organism. The meiosis is the cell division, which occurs to produce the haploid germ cells.

- Which of the following differentiates meiosis from mitosis? mitosis is used for the repair of cells, whereas meiosis creates cells for sexual reproduction. In mitosis four identical daughter cells are produced, whereas two genetically different cells are produced in meiosis meiosis is a form of asexual division, whereas mitosis is a form of sexual division mitosis occurs in prokaryotic cells, whereas meiosis occurs in eukaryotic cellsarrow_forwardWhich of the following is/are true of MITOSIS but NOT MEIOSIS? (May select multiple answers.) O Results in two identical diploid cells. Involves one round of cell division. Involves one round of DNA replication. O Results in four different haploid cells. O Involves two rounds of DNA replication O Involves two rounds of cell division A process required for multicellular organisms to grow bigger. O A process that results in haploid gametes.arrow_forwardWhat are some of the key differences between mitosis and meiosis? Select all that apply. Reduction division occurs in meiosis only. Mitosis produces four daughter cells and meiosis only produces two. Gametogensis occurs in mitosis only. Meiosis produces four daughter cells and mitosis only produces two. Mitosis produces cells that are genetically identical to the parent cell whereas meiosis produces cells that only have half the genetic material of the parents. Both Mitosis and meiosis produce cells that are genetically identical to the parent cell.arrow_forward
- Table below presents the criteria to be used in comparing mitosis and meiosis. Provide the missing information CRITERIA MITOSIS MEIOSIS Presence of synapses presence of crossing over cell type that undergoes cell division number of daughter cells formed DNA content of cells at start of division DNA content of daughter cells genetic consequencesarrow_forwardAll of the following are distinctions between the process of mitosis and meiosis EXCEPT: Group of answer choices homologous chromosomes in meiotic cells conduct synapsis meiotic cells produce genetically distinctive cells meiotic cells go through two cell divisions meiotic cells have homologous chromosomes where mitotic cells do not 2. A scientist working in an IVF (in vitro fertilization) clinic mistakenly produced a human zygote with 45 chromosomes. What biological process could explain how this happened? Group of answer choices failure of an egg to complete meiosis II failure of the egg nucleus to be fertilized by the sperm a non-disjunction in meiotic anaphase occurring in either an egg or sperm incomplete cytokinesis during spermatogenesis after meiosis Iarrow_forwardMeiosis is relatively rare and mitosis is relatively common. Which of the following makes meiosis different from mitosis? Meiosis produces DNA-less cells. We don't fully understand meiosis mechanisms. All gametes are diploid, whereas daughter cells from mitosis are haploid. The resulting cells (gametes) are haploid.arrow_forward
- What processes are responsible for the generation of genetic variation during meiosis, and at what point in meiosis does each occur? Random alignment and separation of homologs that takes place during metaphase I and anaphase I, respectively. Independent assortment of homologous that takes place during anaphase II. Crossing over of non-sister chromatids that take place during prophase I. Replication of DNA during the S phase.arrow_forwardIn a tabular form, differentiate mitosis and meiosis using the following criteria: Chromosome number of daughter cells Stages Synapsis Crossing over Cell type Number of cells formed Genetic consequences Note: More info about genetic consequences and cell type if possible, you can disregard other criteria or parameter of comparison like synapsis, crossing over.arrow_forwardWhich of the following features or events occur ONLY during prophase I of meiosis and do NOT occur during EITHER prophase II of meiosis OR prophase/prometaphase of mitosis? Mark all that apply. Chromatin condensation Crossing-over occurs Homologous chromosomes alignment Spindle assembly Synaptonemal complex formationarrow_forward
- 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.arrow_forwardIn regards to MEIOSIS, give the order of the following events in terms of chromosome number. Question 8 options: meiosis 2 and cytokinesis a total of four cells, each containing 23 chromosomes one cell containing 46 chromosomes meiosis 1 and cytokinesis one cell containing 92 chromosomes two cells containing 46 chromosomesarrow_forwardHow is the outcome of meiosis different from the outcome of mitosis? The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells.arrow_forward
