Biology [1 Mark Question Answer]

Yes, meiosis is responsible for maintaining the chromosome number of a species as meiosis being a reductional division involves formation of daughter cells with half the number of chromosomes.

Mitosis takes place in the body cells or somatic cells of the organisms.

The different phases of mitosis are Prophase, Metaphase, Anaphase and Telophase.

Meiosis results in the formation of ova.

The cell cycle is a series of events that take place in a cell leading to its division and duplication.

Chiasmata - is the point where two homologous non-sister chromatids exchange genetic material in chromosomal crossover during meiosis.

Cytokinesis - It is the division of cytoplasm in which the entire cell splits separating each nuclei.

Karyokinesis - It is the nuclear division where nucleus divides into two.

No, cytokinesis is not necessary after karyokinesis in meiosis I. It generally takes place at the end of meiosis II when the four daughter cells are formed.

In humans, meiosis occurs in testes producing sperms and in the ovaries resulting in ova.
