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 consists of two rounds of division: Meiosis I and Meiosis II.

Front

What is the purpose of Meiosis?

Back

The purpose of Meiosis is to produce gametes for sexual reproduction, ensuring genetic diversity through recombination and independent assortment.

Front

What happens during Prophase I?

Back

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

Front

What is Metaphase I?

Back

In Metaphase I, homologous chromosome pairs align at the cell's equatorial plane, preparing for separation.

Front

What occurs during Anaphase I?

Back

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

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 in each of the two daughter cells, preparing for the second round of division.

Front

What happens during Metaphase II?

Back

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

Front

What occurs during Anaphase II?

Back

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

Front

What is Telophase II?

Back

Telophase II is the final stage of meiosis where the cell divides again, resulting in four genetically diverse gametes.
