16

Select from the following list of statements all of the ways in which meiosis II differs from meiosis I.

Interkinesis doesn't involve the replication of chromosomes, whereas interphase does. Crossing-over doesn't occur in prophase II, whereas it does in prophase I. Sister chromatids separate in anaphase II, whereas homologous chromosomes separate in anaphase I.

At the end of meiosis I, there are two haploid cells, each with two sister chromatids per chromosome. TRUE OR FALSE

True

In animal cells, cytokinesis is accomplished by the formation of a cleavage furrow. TRUE OR FALSE

True

Which of the following events occur during prophase I?

breakdown of the nuclear envelope, condensation of chromosomes, and movement of centrosomes

At the end of meiosis II, there are

four haploid cells, with each chromosome consisting of a single chromatid.

The exchange of genetic material between nonsister chromatids is called crossing-over and occurs during which phase of meiosis?

prophase I

Which of the following events occurs during anaphase I?

separation of homologous chromosomes

Separation of ________ occurs in anaphase II of meiosis.

sister chromatids

What cells in the body are most likely to have originated through the process of meiosis?

sperm and egg cells

What is the overall purpose of meiosis?

to produce four genetically different haploid cells
