Meiosis Definition

Meiosis is a specialized form of cell division essential for sexual reproduction, where one diploid parent cell produces four genetically diverse haploid cells.

Meiosis Phases

Meiosis involves two divisions: Meiosis I and Meiosis II, each with stages like Prophase, Metaphase, Anaphase, and Telophase, facilitating chromosome reduction.

Dot

Prophase I

Chromosomes pair up and exchange genetic material in a process called crossing over, enhancing genetic diversity.

Dot

Metaphase I

Homologous chromosome pairs align at the equatorial plane, preparing for chromosome reduction.

Dot

Anaphase I

Homologous chromosomes separate, reducing the chromosome number by half.

Dot

Telophase I & Cytokinesis

The cell divides, forming two haploid cells, each containing sister chromatids.

Dot

Meiosis II

Sister chromatids are separated, resulting in four haploid gametes.

Dot

Genetic Diversity

Meiosis generates genetic diversity through independent assortment and crossing over, crucial for offspring uniqueness.

Dot

Formation of Gametes

Meiosis produces sperm and eggs, with sperm formation resulting in four sperm cells and egg formation producing one egg and three polar bodies.

Dot

Biological Significance

Meiosis ensures stable chromosome numbers, promotes genetic diversity, and drives evolution, enhancing adaptation and survival.
