Meiosis

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes (sperm or eggs). 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 of Meiosis?

Back

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

Front

What is crossing over?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I, leading to genetic variation.

Front

What occurs during Metaphase I?

Back

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

Front

What is the significance of Anaphase I?

Back

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

Front

What happens during Telophase I?

Back

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

Front

What is the main event of Meiosis II?

Back

The main event of Meiosis II is the separation of sister chromatids, similar to mitosis.

Front

What occurs during Anaphase II?

Back

In Anaphase II, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the outcome of Meiosis?

Back

The outcome of Meiosis is four genetically diverse haploid cells (gametes) from one diploid cell.
