Differences:
# Cells undergoing mitosis divide once, cells undergoing meiosis divide twice. # Mitosis is for cell replication, meiosis is for genetic recombination and to produce reproductive cells # Meiosis does not produce exact copies, mitosis does # Crossing over occurs in meiosis # Mitosis produces diploid cells, meiosis produces haploid Similarities:
# Both duplicate the organism's genome once, before any duplication occurs
# Metaphase plates occur in both # Centrioles exist in both # They share the same basic steps for division # Both occur in eukaryotic cells

∙ 11y agoboth have chromosomes, they both result in no new gene combination, and they both have the same number of chromosomes. meiosis is a sex cell that divides twice homouglous chromosome pair up also meiosis divides twice and makes four new cells.mitosis is a body cell that divides twice and has one deploid it also makes 2 new cells.

Is the DNA different or the same from the parent in mitosis?
First of all, mitosis happens in the body to replicate cells in the skin (for example). Meiosis happens in the sex organs, it makes gametes (sex cells). In mitosis, the one parent cell and the two daughter cells are genetically identical and they have the same number of chromosomes. In meiosis, the one parent cell and the four daughter cells are not genetically identical. The parent cell will have the full number of chromosomes but the daughter cells will only have half the normal number of chromosomes.
Does the cell divide in two during mitosis?
No, because gametes do not divide. Specific cells called "germ cells" give rise to gametes through a process called meiosis. After that gametes do not divide again and simply wait until an opportunity arises in which they can pair up with their other gamete cell and form a zygote.
What generation undergo mitosis in a sporic life cycle?
both the haploid and diploid generations
How does meiosis contribute to the variation in a species?
During meiosis crossing over takes place between homologous chromosomes. Thus genetic material get interchanged and 50 % new combinations are obtained after each meiotic cell division. Thus, meiosis brings heritable variation in the gametes.
What are some factors that affect the rate of mitosis in plants and in animals?
- Metabolic factors like pH, Temperature, nutrients and metabolites - Growth factors like some hormones - Carcinogens (agents that cause cancer)
In a human body give an example of a where mitosis may occur Give an example of where meiosis would occur?
Any time when a cell needs to replicate, it goes through mitosis. The only cells that don't go through mitosis are sex cells.
What are three differences between mitosis and meiosis?
Here are two; mitosis ends in cell division while meiosis ends with gamete division, and mitosis ends with a chromosome number of 2N while meiosis ends with a chromosome number of 1N - give us the third.
What are the similarities and differences between mitosis and meiosis with respect to function location in the organism and the chromosome number haploid or diploid of the daughter cells produced?
Mitosis produces two Diploid Cells while Meiosis produces four haploid cells. The purpose of Mitosis produces new body cells and does not allow for genetic variation, while meiosis allows genetic variation through multiple processes. Meiosis produces sex cells (sperm) , which are key in reproduction of multi-cellular organisms. Each new cell contains half of the number of chromosomes. Meiosis has 2 cellular divisions, while mitosis only has one. They are both necessary to support life, and they both produce Diploid cells in the first division. Also, from a similar topic in Yahoo Answers (Which has a much better explanation) : Mitosis is a type of cell division to produce 2 X genetically identical diploid (2n) cells for growth and repair. Mitosis occcurs in somatic cells (normal body cells. Prior to mitotic division DNA is replicated to produce two identical chromatids attached by a centromere. This is essential so that each new daughter cell formed receives one copy of each chromosome. (One division) Meiosis only occurs in the sex organs to produce 4 X haploid (n), genetically different, gametes for sexual reproduction. Meiosis consists of two divisions: Meiosis I halves the number of chromosomes to give 2 X haploid cells. Meiosis II doubles the number of cells to give 4 X haploid gametes. Two processes during meiosis I increase variation . In prophase I homomolgous chromosomes cross over at points called chiasmata and exchange genetic material. In metaphase I the chromosomes line up along the equator in pairs. This is called random assortment where maternal and paternal chromosomes are arranged at random. Both of these increase variation to produce four genetically different gametes at the end of meiosis II DNA replication only occurs once, before Meoisis I.

What phase of mitosis does the nucleus divide?
The nucleus divides twice in meiosis to give 4 different cells. See the wikipedia page: http://en.wikipedia.org/wiki/Meiosis and the wikepedia diagram: http://en.wikipedia.org/wiki/File:Meiosis_diagram.jpg
What advantage does meiosis give to organisms that reproduce sexually?
Meiosis occurs because it provides a way for genetic variability, since it would be unfavorable for an organism's offspring to have the same weaknesses that it did, as opposed to binary fission or mitosis. In mitosis, the parent and daughter cell will be identical if no genetic mutations occur (which most cells have built-in self-repair mechanisms).
What generation undergo mitosis in a sporic life cycle?
both the haploid and diploid generations
Can you give a sentence using mitosis?
I cannot use mitosis in a sentence.
Give example of mitosis cell division?
Both Mitosis and Mitosis 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 exactly the same DNA strands, while after meiosis each daughter cell will only have half of the DNA strands, sometime the division is not exactly half and half, but that is not really on the right subject. Because meiosis only has half the information that the parent cell had, the call is unable to reproduce by itself. The reason for meiosis is for reproduction of a multi-cellular organism. One daughter cell, from the male of the sides, will try to find a compatible daughter cell, from the female side, and fertilize it. This then becomes an embryo and the specie has succesessfully reproduced.
How many chromosomes will the resulting cells have in mitosis?
This depends both on the cell undergoing mitosis and the stage in mitosis which is currently underway. Humans have 46 chromosomes per cell, but in some stages of mitosis have 92. Dogs have 78 chromosomes, but at some stages of mitosis have 156.

During meiosis crossing over takes place between homologous chromosomes. Thus genetic material get interchanged and 50 % new combinations are obtained after each meiotic cell division. Thus, meiosis brings heritable variation in the gametes.
