   This is an accepted version of this page This is the latest accepted revision, reviewed on 11 February 2025. Cell division producing haploid gametes For the figure of speech, see Meiosis (figure of speech). For the process whereby cell nuclei divide to produce two copies of themselves, see Mitosis. For excessive constriction of the pupils, see Miosis. For the parasitic infestation, see Myiasis ...

3. Leptotene stage - Wikipedia

   en.wikipedia.org/wiki/Leptotene_stage

   Studies in male mouse meiosis have shown that after DNA damaging treatments like gamma irradiation, two types of repair responses occur depending on the meiotic stage: [5] From leptotene to early pachytene, exogenous DNA damage triggers widespread presence of the repair protein gammaH2AX in the nucleus, associated with homologous recombination ...

4. Germ cell - Wikipedia

   en.wikipedia.org/wiki/Germ_cell

   Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis. The lineage of germ cells is called the germline . Germ cell specification begins during cleavage in many animals or in the epiblast during gastrulation in birds and mammals .

5. Cell division - Wikipedia

   en.wikipedia.org/wiki/Cell_division

   Meiosis undergoes two divisions resulting in four haploid daughter cells. Homologous chromosomes are separated in the first division of meiosis, such that each daughter cell has one copy of each chromosome. These chromosomes have already been replicated and have two sister chromatids which are then separated during the second division of ...

6. Origin and function of meiosis - Wikipedia

   en.wikipedia.org/wiki/Origin_and_function_of_meiosis

   Meiosis generates genetic variation in the diploid cell, in part by the exchange of genetic information between the pairs of chromosomes after they align (recombination). Thus, on this view, [28] an advantage of meiosis is that it facilitates the generation of genomic diversity among progeny, allowing adaptation to adverse changes in the ...

7. Meiocyte - Wikipedia

   en.wikipedia.org/wiki/Meiocyte

   A meiocyte is a type of cell that differentiates into a gamete through the process of meiosis. Through meiosis, the diploid meiocyte divides into four genetically different haploid gametes. [1] [2] The control of the meiocyte through the meiotic cell cycle varies between different groups of organisms.

8. Seminiferous tubule - Wikipedia

   en.wikipedia.org/wiki/Seminiferous_tubule

   There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis. The seminiferous tubules are formed from the testis cords that develop from the primitive gonadal cords, formed from the gonadal ridge.
