Question

Assertion: Meiosis II is known as equational or homotypic division.
Reason: Meiosis II produces the same number of chromosomes in the cell.
A: Both assertion and Reason are correct and Reason is correct explanation for assertion
B: Both assertion and Reason are correct and Reason is incorrect explanation for assertion
C: Assertion is correct but reason is incorrect
D: Both Assertion and reason are incorrect.

Answer 1

A single cell divides twice to produce four haploid daughter cells during meiosis. The gametes, or sperm in males and eggs in females, are these cells. The meiosis process is divided into two phases. Each stage is further divided into stages.
Prophase I, Metaphase I, Anaphase I, Telophase I, and Cytokinesis I are the stages of Meiosis I.
Prophase II, Metaphase II, Anaphase II, Telophase II, and Cytokinesis II are the stages of Meiosis II.

Complete answer:
Option A:
Meiosis I (reductional or heterotypic) and Meiosis II are the two cycles that make up a meiotic division (equational or homotypic).
Meiosis II occurs directly after meiosis I, and there is no chromosome replication. Each cell with chromatids divides into two cells, each with chromosomes, during meiosis II. Meiosis II began with two cells; as a result, meiosis II produces four cells, each with chromosomes.
Option a is correct.
Option B:
Meiosis is a mechanism in which a single cell divides twice to create four cells with half the amount of genetic material as the original cell.
So, option B is incorrect.
Option C:
During meiosis II, the sister chromatids inside the two daughter cells separate, resulting in the creation of four new haploid gametes. Meiosis II follows the same mechanics as mitosis, with the exception that each dividing cell has only one set of homologous chromosomes.
So, option C is incorrect.
Option D:
Meiosis II is the second meiotic division, and it is characterised by equational segregation, or sister chromatid separation. From the two haploid cells produced in meiosis I, four haploid cells (with n chromosomes, each consisting of two sister chromatids) are produced.
Option D is incorrect.

Hence, Option A is the correct answer.

Note:
Stages of Meiosis.
Meiosis I
Prophase I
The nuclear envelope breaks down. Chromosomes start to clump together. Spindle fibres begin to appear.
Metaphase I
At the centromere, spindle fibres bind to chromosomes. At the equatorial plate, homologous chromosomes match, ensuring genetic diversity among offspring.
Anaphase I
The homologous chromosomes are pulled in opposite directions.
Telophase I
Spindle fibres vanish. The nuclear envelope has been reformed.
Cytokinesis I
The cell division and cytoplasm resulted in two non-identical diploid daughter cells.
Meiosis II
Prophase II
Chromosomes are formed when chromatin condenses. The nuclear envelope breaks down. Centrosomes move from one pole to the other. The fibres of the spindle are reformed.
Metaphase II
Along the equatorial plate, the chromosomes match. In metaphase I, on the other hand, the chromosomes were in homologous pairs.
Anaphase II
Sister chromatids are attracted to poles on opposite sides of the chromosome.
Telophase II
The spindle fibres vanish as the nuclear envelope redevelops.
Cytokinesis II
The cytoplasm and cell differentiate, resulting in four haploid daughter cells that are not identical.
