when is it Meiosis instead of Mitosis??

Question

so i get the difference between the two, i just dont get WHEN meiosis happens instead of mitosis. please help!!!!

Answer 1

Meiosis deals with sex cells. Sex cells are reproductive cells produced in the sex organs. Sex cells are made during meiosis . Hence, meiosis is a kind of cell reproduction that forms eggs and sperm.

Mitosis is cell reproduction in which two identical cells are made from one cell. Each new cell grows in size until it too is ready to reproduce using mitosis. All body cells in humans are formed by mitosis. Except for the above mentioned meiosis.

Answer 2

Meiosis happens when an organism is producing sperm or eggs. So meiosis only happens in the gonads, and mitosis happens anywhere that more cells are needed.

Answer 3

Mitosis takes place in the vegetative or somatic cells like all body cells------for growth, repair and regeneration, development including embryonic development. Further, the cells produced as a result of mitosis are similar in genetic make up like chromosome number and genetic information (genes).
However, nature has devised a special type of cell division for producing the reproductive cells called as Gametes(sperm in case of males and eggs in case of females).These cells are produced in gonads (Testis in males and ovaries in case of females). The gonads have stem cells called mother cells. Each mother cell (2x)undergoes gametogenesis(meiosis) to produce haploid(x) cells . The process is complex one. Each complete meiotic division results in the formation of 4 daughter cells with half number of the chromosomes(haploid-x). Further, during the process an important phenomenon takes place called as crossing over of homologous chromosomes which brings genetic recombination in the chromosomes. Thus the daughter cells produced are not genetically identical. The haploid number is important for restoration of chromosome number in the zygote(basic cell of Future organism) during fertilization. So, precisely the aim of the meiosis is to maintain the constant number of chromosomes within the individuals of a species and also bring variations among the individuals of the same species. The variations are the sources of evolution-----origin of new species from the old or existing species.

"My toes form through mitosis."
