Meiosis: Prophase I consists of five stages and lasts longer than prophase of mitosis. The five stages of meiotic prophase I are leptotene, zygotene, pachytene, diplotene, and diakinesis. These five stages do not occur in mitosis. Genetic recombination and crossing over take place during prophase I.
What are 4 differences between mitosis and meiosis?
Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment. … Mitosis includes one division , while meiosis includes two.
What is not common to both mitosis and meiosis?
Which of the following is NOT common to both mitosis and meiosis? The DNA in the chromosomes is duplicated. … There is a reduction in the number of chromosomes in daughter cells. The chromosomes align themselves at opposite ends of the cells.
What are at least 3 ways meiosis and mitosis differ?
Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
How is meiosis similar to mitosis how is it different?
Mitosis is done in somatic cells, while meiosis takes place in gametes. Mitosis occurs in both, asexual and sexual reproduction, while meiosis is characteristic of only sexual reproduction. There is no crossing over in mitosis, only in meiotic division.
Which is the correct order of events in meiosis?
Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.
What are 2 events that are common to both mitosis and meiosis?
Aside from these two distinct purposes, both mitosis and meiosis occur in multiple stages during which the same general things happen: DNA replication and condensation, nuclear membrane degradation, spindle formation, chromosomal segregation and nuclear reformation.
What are the phases of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.
What are two errors that can occur during meiosis?
Other mistakes that can occur during meiosis include translocation, in which part of one chromosome becomes attached to another, and deletion, in which part of one chromosome is lost entirely.
