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.
Does meiosis make identical or unique cells?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
How does meiosis produce unique cells?
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. … The result is 4 haploid daughter cells known as gametes.
Why does meiosis not produce identical cells?
Two gametes in each pair of cells produced by meiosis are not identical because recombination of alleles (genes) present on two homologous chromosomes occurs during meiosis.
Which of the following distinguishes meiosis from mitosis?
Mitosis occurs in somatic cells and meiosis occurs in germ cells. The crossing over event takes place in meiotic cell division and not in mitosis. Meiosis produces four n daughter cells.
How is meiosis similar to mitosis how is it different?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
What is unique about the cells that are created at the end of meiosis II?
Meiosis II results in four haploid daughter cells, each with the same number of chromosomes. However, each chromosome is unique and contains a mix of genetic information from the maternal and paternal chromosomes in the original parent cell.
Why are the two cells produced by the cell cycle genetically identical?
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies – or ‘replicates’ – its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
Are the four daughter cells of meiosis genetically identical or different from one another?
The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. The main differences between mitosis and meiosis occur in meiosis I.
Is meiosis genetically identical or different?
The nuclei resulting from meiosis are never genetically identical, and they contain one chromosome set only—this is half the number of the original cell, which was diploid. The differences in the outcomes of meiosis and mitosis occur because of differences in the behavior of the chromosomes during each process.
Does meiosis produce identical diploid cells?
When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells. … In contrast, meiosis is considered a “reductional” form of cell division that occurs in diploid germ cells.
Do both mitosis and meiosis produce genetically identical cells?
You want all your new cells to have the same DNA as the previous cells. The goal of meiosis is to produce sperm or eggs, also known as gametes. The resulting gametes are not genetically identical to the parent cell.
Mitosis vs. Meiosis.
|Are daughter cells identical to each other?||Yes||No|
Which of the following is unique to mitosis and not a part of meiosis 1?
The correct answer is c. Homologous chromosomes behave independently. In the case of mitosis, there is no recombination or crossing over between…
