Meiosis

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells from one diploid cell. It is essential for sexual reproduction.

Front

What are the two main stages of Meiosis?

Back

The two main stages of Meiosis are Meiosis I and Meiosis II.

Front

What happens during Prophase I?

Back

During Prophase I, homologous chromosomes pair up and exchange genetic material through a process called crossing over.

Front

What is the significance of Metaphase I?

Back

In Metaphase I, homologous chromosome pairs align at the cell's equatorial plane, which is crucial for the proper segregation of chromosomes.

Front

What occurs during Anaphase I?

Back

During Anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell.

Front

What is Telophase I?

Back

Telophase I is the stage where the cell divides into two daughter cells, each with half the number of chromosomes.

Front

What is Prophase II?

Back

Prophase II is the stage where the chromosomes condense again and the nuclear envelope breaks down in each of the two daughter cells.

Front

What happens during Metaphase II?

Back

In Metaphase II, chromosomes line up individually along the equatorial plane of the cell.

Front

What is Anaphase II?

Back

Anaphase II is when sister chromatids are pulled apart to opposite poles of the cell.

Front

What occurs during Telophase II?

Back

During Telophase II, the nuclear envelope reforms around each set of chromosomes, and the cell divides, resulting in four haploid cells.
