what are three main differences between mitosis and meiosis?

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.

Both mitosis and meiosis occur in cells of plants and animals. ... Meiosis is a process of sexual reproduction that produces new gene combinations, which differs from mitosis, itself an asexual process of cell division. Meiosis occurs in reproductive plant and animal cells like spores, sperm and egg cells.

Comparison of the processes of mitosis and meiosis. 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.

1 Answer. Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm. They are both two stages in the cell cycle.

The difference between mitosis and meiosis is A. Crossing over occurs in mitosis but not meiosis B. in mitosis, homologous pairs of chromosomes line up at the metaphase plate C. in meiosis, sister chromatids exchange genetic information with one another D.

Answer and Explanation: Mitosis takes place in somatic cells and produces two diploid daughter cells. Meiosis takes place in gametic cells and it produces four haploid daughter cells with varied genetic composition (due to crossing over and independent assortment of chromosomes).

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.

1 Answer. 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.

What is the key difference between anaphase I in meiosis and anaphase in mitosis? Answer: A key difference between mitosis and meiosis is that sister chromatids remain joined during anaphase I in meiosis, whereas in anaphase of mitosis they separate.

Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis.

Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

Mitosis and meiosis are both processes which describe the production of new cells. Mitosis produces 2 daughter cells which are genetically identical to the parent cell. ... Meiosis is used to produce gametes (sperm and egg cells), the cells of sexual reproduction.

The main difference between animal cell mitosis and plant cell mitosis is that in animal cell undergoes cell furrowing while plant cell do not because of the rigid cell wall. The major difference is during the last phase of mitosis , that is telophase. And thus, cytokinesis occurs differently in both the cells.

Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase. ... The resulting offspring is genetically different in the case of meiosis, while the offspring is identical in the case of mitosis.

Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

The major difference between meiosis II and mitosis is the ploidy of the starting cell. Meiosis II begins with two haploid cells, which have half the number of chromosomes as somatic cells. ... Mitosis begins with a diploid cell. It will divide into two sister cells, both of which are also diploid.

Mitosis vs. meiosis. Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell.
