How does mitosis and meiosis differ? Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Which event occurs during both mitosis and meiosis?
Both mitosis and meiosis entail four main events: 1) a reproductive signal, 2) replication of nuclear DNA, 3) segregation of the replicated nuclear DNA into new daughter nuclei, and 4) division of the cytoplasm, or cytokinesis to produce new daughter cells.
Which of the following event does not occur in mitosis?
B), replication of DNA does not occur in mitosis. Replication of DNA occurs during S phase, an entirely different phase of cell division where the
Which event happens in meiosis II but not in meiosis I?
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
Does Synapsis occur in mitosis?
Synapsis takes place during prophase I of meiosis. Mitosis also has prophase, but does not ordinarily do pairing of two homologous chromosomes.
Related question for How Does Mitosis And Meiosis Differ?
What is a difference between the processes of mitosis and meiosis quizlet?
What are the principal differences between mitosis and meiosis? Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells.
Which two events are not shared by mitosis and meiosis?
The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Which events occur during both mitosis and meiosis quizlet?
Both mitosis and meiosis are associated with cytokinesis. The end result of both are daughter cells produced from a parent cell. The fundamental sequence of events in mitosis is the same as in meiosis (in meiosis it happens twice).
Which of the following is true about both mitosis and meiosis?
The answer is D. Meiosis involves 2 rounds of cell division; mitosis involves one. Meiosis gives rise to 4 daughter cells; mitosis gives rise to 2. The 2 daughter cells of mitosis are identical to each other; the 4 daughter cells of meiosis are different from each other and different from the cell that produced them.
Which of the following does not occur during mitosis in somatic cell?
Synapsis is not a chracteristic feature during mitosis in somatic cells.
Which of the following events does not take place during mitosis in somatic cells?
Crossing over occurs during meiosis I and not mitosis.
What events occur during meiosis I and meiosis II?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
Which process occurs during anaphase of mitosis quizlet?
Which of the following events occurs during anaphase of mitosis? The sister chromatids are pulled apart toward opposite sides of the cell.

What are 3 main differences between mitosis and meiosis?
The differences between mitosis and meiosis
|• Maintenance of chromosome number (diploid)||• Reduction/halving of chromosomes (haploid)|
|• Takes place in somatic cells/growth||• Occurs in reproductive cells/gonads/produces gametes|
|• No crossing over/no variations||• Crossing over takes place/variation occurs|
