Growth, Development, and Reproduction of Organisms: Cell Division: Mitosis and Meiosis

Meiosis I

Description

Meiosis I

Meiosis is a specialized type of cell division that reduces the chromosome number by half, producing gametes (sperm and egg cells) in sexually reproducing organisms. Unlike mitosis, which creates genetically identical cells, meiosis introduces genetic diversity through crossing over and...

Transcript

Meiosis is a type of cell division that occurs in reproductive cells. This process creates four new cells, each with half the number of chromosomes.

It occurs in two stages: Meiosis I and Meiosis II.

In this lesson, let's learn about Meiosis I, which has four stages.

First comes Prophase I, where homologous chromosomes—pairs o...
