what is the difference between meiosis and mitosis?

Answer 1

meiosis - cell divides but chromosomes are not duplicated. the product is two haploid cells with slightly different DNA (due to crossing over of chromosomes when they line up in metaphase)
mitosis - cell divides into two identical daughter cells. if the mother cell is diploid, the two daughter cells will be too

Answer 2

Difference Between Meiosis And Mitosis

Answer 3

Mitosis is the cell division which keeps happening in our body. It does not change the number of chromosomes in the cell. This occurs in all somatic cells of the body. It helps to make new cells and helps us grow.
Meiosis occurs in the gametes, or reproductory cells of the body. During meiosis, the number of chomosomes is halved, i.e, one cell formed will have half the no. of chromosomes, the other cell will have other half chromosomes. This is to ensure that that when fertilisation occurs, the 2 gametes, i.e. ovum and sperm will have half the no. of chromosomes each, which will help to keep no. of chromosomes constant, with respect to somatic cells, and will help keep the species constant. Thus, meiosis is called Haploid Division. It helps in variation in the offspring, because half chromosomes are from father and half from the mother.
It also helps in Sex Determination
The female ovum has 2 'X' chromosomes and the male sperm has 1 'X' and one 'Y' chromosome. The meiosis takes place such that in the 2 sperms produced, one will have a 'X' chromosome and one will have a 'Y' chromosome. And in female, the 2 ova will have an 'X' chromosome each. Thus when fertilisation takes place, if the sperm containing 'X' chromosome meets the ovum, the zygote will have 2 'X' chromosomes, or the XX condition, of females. Thus the offspring will be a female.
If the sperm with 'Y' chromosome meets the ovum, the zygote will have one 'X' and one 'Y' chromosome, or XY condition, of males. Thus the offspring will be a male.
Thus mitosis helps us to grow by producing new cells in the Diploid condition, while Meiosis helps in production of haploid gametes to form new offsprings.
I hope this answers your query.

Answer 4

In biology, mitosis is the process by which a cell separates its duplicated genome into two identical halves. It is generally followed immediately by cytokinesis which divides the cytoplasm and cell membrane. This results in two identical daughter cells with a roughly equal distribution of organelles and other cellular components. Mitosis and cytokinesis together is defined as the mitotic (M) phase of the cell cycle, the division of the mother cell into two daughter cells, each the genetic equivalent of the parent cell.

Mitosis occurs exclusively in eukaryotic cells. In multicellular organisms, the somatic cells undergo mitosis, while germ cells — cells destined to become sperm in males or ova in females — divide by a related process called meiosis. Prokaryotic cells, which lack a nucleus, divide by a process called binary fission.

meiosis is the process that transforms one diploid cell into four haploid cells in eukaryotes in order to redistribute the diploid's cell's genome.

Meiosis forms the basis of sexual reproduction and can only occur in eukaryotes. In meiosis, the diploid cell's genome, which is composed of ordered structures of coiled DNA called chromosomes, is replicated once and separated twice, producing four sets of haploid cells each containing half of the original cell's chromosomes. These resultant haploid cells will fertilize with other haploid cells of the opposite gender to form a diploid cell again. The cyclical process of separation by meiosis and genetic recombination through fertilization is called the life cycle. The result is that the offspring produced during germination after meiosis will have a slightly different blueprint which has instructions for the cells to work, contained in the DNA. This allows sexual reproduction to occur.

Answer 5

the main difference is that mitosis occurs in somatic cells while meosis occur in germ cells.also the daughter cell in mitosis is replica of parent cell in genome while the daughter cell in meosis isn`t.
