Which best represents one fundamental difference between the processes of mitosis and meiosis? Meiosis results in 4 haploid cells, and mitosis results in 2 diploid cells. … Parent cells divide by mitosis to produce the offspring.
What is the main 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 process occurs in both mitosis and meiosis *?
Which of the following occur in both mitosis and meiosis? Explanation: The separation of sister chromatids is the only item of the answer choices that occurs in both mitosis and meiosis. Prophase II and metaphase II only occur in meiosis, as does recombination between homologous chromosomes.
Which process can occur during meiosis and would cause the zygote to contain either too many or too few chromosomes?
Nondisjunction happens when a chromosome pair doesn’t separate during meiosis. As a result, one of the gametes contains extra chromosomes, while others have too few.
What do mitosis and meiosis have in common quizlet?
What does mitosis and meiosis have in common? They both are involved in cell division. What is asexual reproduction? When a new organism is produced from one organism.
How do the differences between cells produced by meiosis and mitosis lead to changes in the next generation quizlet?
The next generation will have smaller cells because cells produced by meiosis have smaller cell membranes than cells produced by mitosis. D. The next generation will have greater genetic variation because,unlike mitosis cells, meiosis cells are randomly fertilized, and chromosomes are independently assorted.
How are mitosis and meiosis similar and different?
Mitosis has only one round of cell division, while meiosis has two. … Mitosis produces daughter cells (diploid cells) that are identical to the parent cell, while mitosis produces haploid/monoploid cells that only have half of the normal number of chromosomes.
What are 4 similarities between mitosis and meiosis?
The similarities between mitosis and meiosis are as follows:
- Mitosis and meiosis take place in the cell nuclei.
- Both involve cell division.
- Both the processes occur in the M-phase of the cell cycle.
- In both cycles, the stages are common – metaphase, anaphase, telophase and prophase.
- Synthesis of DNA occurs in both.
What difference does it make whether nondisjunction occurs during meiosis I or meiosis II?
Nondisjunction only results in gametes with n+1 or n–1 chromosomes. Nondisjunction occurring during meiosis II results in 50 percent normal gametes. Nondisjunction during meiosis I results in 50 percent normal gametes. Nondisjunction always results in four different kinds of gametes.
What is the difference between meiosis 1 and meiosis 2?
However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
What are the three 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|
What are the two main differences between mitosis and meiosis?
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 gives nuclei with the same number of chromosomes as the mother cell while meiosis gives cells with half the number.
