Meiosis in Animals (55x90cm)

A “Meiosis in Animals” (55×90 cm) educational chart provides a stepwise, full-color visual explanation of the process of meiosis as it occurs in animal cells, emphasizing the formation of gametes (sperm and eggs) and the role of meiosis in genetic diversity.​

Features and Educational Content

Size and Material: The chart measures 55×90 cm, is usually multicolored, thermally laminated for durability, and water- and dust-resistant to suit repeated classroom or laboratory use.​

Stages of Meiosis Illustrated:

Meiosis I (Reductional division):

Prophase I: Homologous chromosomes pair up and crossing over occurs, exchanging genetic material. The nuclear envelope dissolves, and chromosome pairs become visible.​

Metaphase I: Homologous pairs align at the equator (metaphase plate) of the cell.​

Anaphase I: Pairs separate, with one chromosome from each pair pulled to opposite sides; sister chromatids remain together.​

Telophase I: Two new haploid cells are formed, each with half the chromosome number.​

Meiosis II (Equational division, similar to mitosis):

Prophase II: Chromosomes re-condense in each haploid cell.​

Metaphase II: Chromosomes align singly at the equator in both cells.

Anaphase II: Sister chromatids separate and are pulled to opposite poles.​

Telophase II: Four genetically unique haploid gametes are produced at the end of cytokinesis.​

Diagram Highlights:

Clearly labeled stages with arrows showing progression.

Chromosome number changes visualized through each division.

Genetic diversity mechanisms, like crossing over and independent assortment, are visually emphasized.​

Teaching Utility:

The chart is ideal for teaching zoology, genetics, and reproductive biology.

It often includes concise, stage-specific explanations for quick reference in practical or theory lessons.​

This chart enables students to easily distinguish meiosis from mitosis, understand genetic variation in animals, and visualize key events essential for gamete formation and sexual reproduction.
