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 daughter cells. 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 equator, 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 the 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

In Prophase II, the chromosomes condense again, and the nuclear envelope breaks down if it was reformed.

Front

What is Metaphase II?

Back

In Metaphase II, chromosomes line up at the equator of the cell, similar to Metaphase in mitosis.

Front

What occurs during Anaphase II?

Back

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