BIOL-1306 Meiosis

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells, each genetically distinct from the parent cell.

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, leading to genetic variation.

Front

Define Metaphase I in Meiosis.

Back

In Metaphase I, homologous chromosome pairs align along the metaphase plate, preparing for separation.

Front

What happens 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 haploid cells, and the nuclear membrane may reform.

Front

Explain the significance of Telophase II.

Back

In Telophase II, the chromosomes decondense, the nuclear membrane reforms, and four haploid daughter cells are produced.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows mitosis or meiosis, where the cytoplasm divides, resulting in two separate cells.

Front

Describe the difference between Cytokinesis in plants and animals.

Back

In plants, a cell plate forms during cytokinesis, while in animals, a cleavage furrow forms to separate the cells.

Front

What is the role of Prophase II?

Back

In Prophase II, the chromosomes condense again, and the nuclear envelope breaks down in preparation for the second meiotic division.

Front

Define Metaphase II.

Back

In Metaphase II, duplicated chromosomes line up at the metaphase plate, similar to metaphase in mitosis.
