Meiosis phase identification

Front

What is the first phase of meiosis?

Back

Prophase I

Front

What occurs during Metaphase I of meiosis?

Back

Homologous chromosomes align at the cell's equatorial plate.

Front

What is the significance of Anaphase I in meiosis?

Back

Homologous chromosomes are pulled apart to opposite poles.

Front

What happens during Telophase I?

Back

The cell divides into two daughter cells, each with half the number of chromosomes.

Front

What is crossing over and when does it occur?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I.

Front

What is the role of spindle fibers during meiosis?

Back

Spindle fibers help separate chromosomes during Anaphase.

Front

What phase follows Telophase I in meiosis?

Back

Prophase II

Front

What is the outcome of Meiosis II?

Back

Four genetically diverse haploid cells are produced.

Front

What is the difference between Anaphase I and Anaphase II?

Back

In Anaphase I, homologous chromosomes are separated; in Anaphase II, sister chromatids are separated.

Front

What is genetic variation and how is it achieved in meiosis?

Back

Genetic variation is the diversity in gene frequencies, achieved through crossing over and independent assortment.
