Describe the process of mitosis and meiosis.​
____ [38]

Answer:

Mitosis:

Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.

Meiosis:

Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.

What are the phases in meiosis and explain
densk [106]

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.
