What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of 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 occurs during Prophase I of meiosis?

Back

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

Front

What is the significance of crossing over in meiosis?

Back

Crossing over increases genetic diversity by allowing the exchange of genetic material between homologous chromosomes.

Front

What happens during Metaphase I?

Back

During Metaphase I, homologous chromosome pairs align at the cell's equatorial plane.

Front

What is the outcome of Anaphase I?

Back

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

Front

What occurs during Telophase I?

Back

During Telophase I, the cell divides into two haploid cells, and the nuclear membrane may reform.

Front

What is the main difference between Meiosis I and Meiosis II?

Back

Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids.

Front

What happens during Prophase II?

Back

During Prophase II, the chromosomes condense again, and the nuclear envelope breaks down if it reformed during Telophase I.

Front

What is the role of Metaphase II?

Back

In Metaphase II, the chromosomes line up at the equatorial plane, similar to mitosis.
