CELL DIVISION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many rounds of division do cells go through in meiosis
A
one
B
four
C
two
D
none
Explanation: 

Detailed explanation-1: -Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Detailed explanation-2: -Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation. Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis.

Detailed explanation-3: -To accomplish this feat, meiosis, unlike mitosis, involves a single round of DNA replication followed by two rounds of cell division (Figure 1).

Detailed explanation-4: -During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes.

Detailed explanation-5: -Meiosis involves two rounds of cell division and produces four non-identical haploid daughter cells.
