Meiosis

If the gametes produced by a given organism contain 6 chromosomes, how many chromosomes are found in that organism's body cells?

12

If an organism's diploid cells contain 8 chromosomes, how many chromosomes do it's haploid cells contain?

4

In what phase of meiosis are tetrads separated as homologous chromosomes are pulled to opposite poles of the cell?

Anaphase I

In what phase of meiosis are sister chromatids separated and pulled to opposite ends of the cell?

Anaphase II

Which of the following best describes what happens during a cross-over event?

Chromatids of homologous chromosomes exchange corresponding segments

One full cycle of meiosis produces

Four haploid cells

Which of the following statements best describes the major difference between anaphase of mitosis and anaphase I of meiosis?

In anaphase I, homologous pairs are separated but sister chromatids stay joined together

Which of the following statements best describes the major difference between metaphase I of meiosis and metaphase of mitosis?

In metaphase I, tetrads sets of homologous chromosomes stay together as they line up along the center of the cell

Which of the following statements best describes the major difference between prophase I of meiosis and prophase of mitosis?

In prophase I, tetrads of homologous chromosomes form and crossing over occurs

Which of the following statements is true of meiosis?

It divides one diploid cell into four haploid cells

Which of the following best describes the process of meiosis?

It is carried out in cells that are involved in sexual reproduction

In what phase of meiosis are tetrads of homologous pairs lined up along the center of the cell and attached to the spindle fibers?

Metaphase I

At what stage of meiosis does crossing over occur?

Prophase I

Crossing over occurs when

homologous chromosomes join together to form tetrads during prophase I
