Focuses on the second division of meiosis and the mechanisms that generate genetic diversity, including independent assortment and crossing over.
Homologous chromosome pairing occurs only in meiosis during prophase I, leading to genetic recombination.

Telophase II results in four haploid cells, not diploid cells.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
There is no DNA replication between meiosis I and II.

Mitosis maintains the chromosome number, while meiosis reduces it by half, ensuring haploid gamete formation.

During telophase II, the nuclear membrane reforms around the newly separated chromosomes.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
Mitosis produces genetically identical cells, while meiosis introduces genetic variation through recombination.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
There is no DNA replication between meiosis I and II.

During prophase, centrosomes migrate to opposite poles to form the mitotic spindle.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
Spindle fibers attach to kinetochores and help in the movement and separation of chromatids or homologous chromosomes during cell division.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
Meiosis consists of two rounds of division (meiosis I and meiosis II), not just one.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
Meiosis produces genetically varied cells due to crossing over and independent assortment, not identical ones.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
Meiosis consists of two divisions (meiosis I and II) and produces haploid cells, contributing to genetic variation.
