LeThe Formation of Gametes through Meiosis wall chart is a detailed educational resource designed to explain how sex cells are produced through the process of meiosis. This poster clearly introduces what meiosis is, where it occurs in the human body, and why it is essential for sexual reproduction and genetic variation. The introductory text explains diploid and haploid chromosome numbers, fertilisation, and the formation of a zygote, providing essential biological context.

The chart includes a comprehensive, step-by-step illustration of meiosis in an animal cell, covering interphase, meiosis I, and meiosis II. Each phase is clearly labelled, showing chromosome pairing, crossing over, chiasmata formation, spindle fibre activity, and the separation of homologous chromosomes and sister chromatids. These diagrams help learners visualise how four genetically different haploid cells are formed.

Detailed sections explain how meiosis takes place, highlighting crossing over between non-sister chromatids and the formation of bivalents. Additional diagrams focus on chromosome structure, centromeres, and the exchange of genetic material.

The lower section of the wall chart compares spermatogenesis and oogenesis in mammals, explaining egg cell development, sperm cell structure, and the relative size of sperm and egg cells. This poster is ideal for classrooms, laboratories, and revision areas, supporting clear understanding of reproduction, inheritance, and genetic diversity.
