Question

write a short note on mitosis and meiosis​

Answer 1

Answer:

Explanation:

Mitosis is a nuclear division giving rise to genetically identical cells in which the chromosome number is maintained by the exact duplication of chromosome. Meiosis is a reduction division in which the chromosome number is halved from diploid to haploid.

Answer 2

Answer:

their are two stages of mitosis. these are (1)karyokinesis or nuclear division and (2)cytokinesis or cytoplasmic division. karykinesis takes place in further four phases. viz prophase, metaphase, anaphase and telophase.

meiosis is completed through two stages .those two stages are meiosis-I and meiosis-II .in meiosis-I recombination/crossing over occer between homologous chromosomes and thereafter those homologous chromosomes are divided into two groups and thus two haploid cells are formed. meiosis -II is just like mitosis
