Phases of Meiosis

Front

What is Prophase 1 in Meiosis?

Back

Prophase 1 is the first stage of meiosis where homologous chromosomes pair up and exchange genetic material through a process called crossing over.

Front

What is Meiosis 1?

Back

Meiosis 1 is the first division in meiosis where homologous chromosomes are separated into two daughter cells, reducing the chromosome number by half.

Front

What is Meiosis 2?

Back

Meiosis 2 is the second division in meiosis that resembles mitosis, where sister chromatids are separated into four haploid cells.

Front

What occurs during Anaphase 1?

Back

During Anaphase 1, homologous chromosomes are pulled apart to opposite poles of the cell.

Front

What is Prophase 2?

Back

Prophase 2 is the stage in meiosis where the chromosomes condense again and the nuclear envelope breaks down, preparing for the second meiotic division.

Front

Define Metaphase 1.

Back

Metaphase 1 is the stage in meiosis where homologous chromosome pairs align at the cell's equatorial plane.

Front

What happens during Telophase 1?

Back

During Telophase 1, the separated chromosomes reach the poles, and the cell begins to divide into two daughter cells.

Front

What is the significance of crossing over in Prophase 1?

Back

Crossing over increases genetic diversity by exchanging segments of DNA between homologous chromosomes.

Front

What is the difference between Meiosis 1 and Meiosis 2?

Back

Meiosis 1 reduces the chromosome number by separating homologous chromosomes, while Meiosis 2 separates sister chromatids without further reducing the chromosome number.

Front

What is the role of spindle fibers in Anaphase 1?

Back

Spindle fibers attach to homologous chromosomes and pull them apart to opposite poles during Anaphase 1.
