How is mitosis and meiosis are different?
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.
What is the difference between 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.
What is a major difference between mitosis and meiosis 1 quizlet?
What is a major difference between mitosis and meiosis I in a diploid organism? Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I. A student is looking through his light microscope (~450 X) at a squashed and stained onion root tip.
Is the parent cells haploid or diploid quizlet?
They are diploid because they have 2 copies of each chromosome. A chromosome from a male parent corresponds with a chromosome from female parent.
What are four differences between meiosis and mitosis?
Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives nuclei with the same number of chromosomes as the mother cell while meiosis gives cells with half the number. Mitosis includes one division , while meiosis includes two.
What are three key differences between mitosis and meiosis?
The differences between mitosis and meiosis
| Mitosis | 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 |
Does the parent cell in meiosis start off as deployed or haploid?
The parent cell in meiosis starts off as diploid. It replicates its DNA, then undergoes two sets of cell divisions. The first separates homologous chromosomes, and the second separates sister chromatids. Ultimately, this produces four haploid cells that result from meiosis.
