Meiosis Flashcard Review

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).

Front

What are the two main stages of Meiosis?

Back

The two main stages of Meiosis are Meiosis I and Meiosis II.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells (2n) contain two complete sets of chromosomes, one from each parent, while haploid cells (n) contain only one set of chromosomes.

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.

Front

What is fertilization?

Back

Fertilization is the process where a sperm cell and an egg cell combine to form a zygote.

Front

What is the significance of crossing over?

Back

Crossing over increases genetic diversity by allowing the exchange of genetic material between homologous chromosomes.

Front

What is the end result of Meiosis?

Back

The end result of Meiosis is four genetically unique haploid cells.

Front

How many times does the cell divide in Meiosis?

Back

The cell divides twice in Meiosis, resulting in four daughter cells.

Front

What is Metaphase I?

Back

Metaphase I is the stage in Meiosis I where homologous chromosomes line up at the cell's equatorial plane.

Front

What is Anaphase II?

Back

Anaphase II is the stage in Meiosis II where sister chromatids are pulled apart to opposite poles of the cell.
