Cell Division Review

Front

What is crossing over?

Back

Crossing over is a process during meiosis where homologous chromosomes exchange genetic material, leading to genetic variation in the offspring.

Front

What phase of cell division occurs before metaphase?

Back

Prophase is the phase that occurs before metaphase in cell division.

Front

What is the haploid number if the diploid number is 18?

Back

The haploid number is 9.

Front

What does meiosis produce?

Back

Meiosis produces 4 genetically different, haploid cells.

Front

What phase of cell division is characterized by the separation of sister chromatids?

Back

Anaphase is the phase where sister chromatids are pulled apart to opposite sides of the cell.

Front

Define diploid.

Back

Diploid refers to a cell that contains two complete sets of chromosomes, one from each parent.

Front

Define haploid.

Back

Haploid refers to a cell that contains only one set of chromosomes.

Front

What is the main purpose of meiosis?

Back

The main purpose of meiosis is to produce gametes (sperm and eggs) for sexual reproduction.

Front

What happens during prophase?

Back

During prophase, chromosomes condense, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals, which can lead to different traits.
