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.

MITOSIS:

prophase:
homologous chromosomes do not undergo pairing chromosomes are not seen crossing over and formation of the chiasmata are absent

metaphase:
all the chromosomes form a single group and occupy the equator with the centromeres aligning along the same line the centre of mass of homologous chromosomes are connected to both the poles of the spindle

anaphase:
centromeres divide the chromatic became daughter chromosomes the combination of gene in the chromosomes are altered

telophase:
both the members of the homologous chromosomes are present together in the daughter cells

occurence :
usually occur in the somatic cells

functions:
help in the growth and the repair maintenance of the nuclear cytoplasmic ratio a sexual reproduction and vegetative propagation can occur through Mitosis

daughter cells:
produce identical diploid daughter cells

MEIOSIS:

prophase:
how is chromosomes undergo paining forming bivalent chromosomes are seen crossing over and formation of Chiasmata occur

metaphase:
the chromosomes form to groups 1 on either side of the equator in metaphase the centre of mass of the two members of each homologous pair face opposite poles of the spindle and are at equal distance from the equator they are connected to only one pole of spindle

anaphase:
the Saint Thomas do not divide during anaphase 1 the sister chromatids remain together in anaphase to centromeres divide and chromatid become daughter chromosomes due to crossing over there will be the combination of genes

telophase :
the maternal ,paternal chromosomes of the homologous pair are not present together in the daughter cell only one of them is present

occurance:
usually seen in germ cells producing gametes

functions:
helps in the formation of gametes with genetic variations due to crossing over and random assortment of maternal and paternal chromosome involved in sexual reproduction

daughter cells:
produces four haploid cells from a diploid cell which differ from each other genetically (recombination of genes )

hope it may be helpful for u

be brainly

masterzx: I mean the answer explains things but this question comes in the paper for two marks so not efficient.
