What are similarities and differences of mitosis and meiosis?

Answer 1

Mitosis vs. MeiosisBoth mitosis and meiosis are mechanisms that describe cell division. The difference is particularly noticeable when one looks at the DNA in the cell's nucleus. After mitosis, each of the daughter cells will have exact same DNA strands, while after meiosis each daughter cell will only have half of the DNA strands. (Sometimes the division is not exactly half/half, but that is not important for this answer).

Because meiosis only has half the information that the parent cell had, the cell is (as far as we know) unable to reproduce by itself. The reason for meiosis is for reproduction of a multi-cellular organism as well as genetic diversity due to crossing over. One daughter cell (from the male of the species) will try to find a compatible daughter cell (from the female of the species) and fertilize it. This then becomes and embryo and the specie has successfully reproduced. And this is how you, the reader, came into existence.

Other characteristics:

• Parent cell - full set of chromosomes in both mitosis and meiosis (2n).
• Number of divisions - mitosis 1; meiosis 2.
• Chromosome number of daughter cells - mitosis full set (2n) and meiosis half set (n).
• Crossing over - mitosis no; meiosis yes
• Paired homologues - mitosis no; meiosis yes
• DNA of daughter cells - mitosis identical to parent; meiosis daughter cells different
• Number of DNA replications - mitosis 1; meiosis 2
• Number of daughter cells - mitosis 2; meiosis 4
• Type of cells - mitosis somatic; meiosis sex cells

Answer 2

Mitosis and meiosis are both cell division. Meiosis is a longer version of mitosis, splitting more times. In Meiosis only comes in humans, animals, plants, and fungi. Mitosis happens in all organisms. Meiosis goes through mitosis twice going through, Prophase 1 and 2, Metaphase 1 and 2, Anaphase 1 and 2, and Telophase 1 and 2

Answer 3

the similarities is that they both are the prossess of making cells. the difference is that mitosis makes regular cells with for humans 46 chromosomes, and meiosis is making reproductive cells which for humans have half the chromosomes so they have 23 chromosomes. how i remember this is that for meiosis it sounds like it's missing the T so its missing half the chromosomes.

Answer 4

Both are division of cells. Also both have a single division with genetically identical cells as the parent cell

Answer 5

They are both forms of cell division
