SAT Cell Division: Mitosis and Meiosis 2

Question 1

Which event occurs during meiosis I that distinguishes it from mitosis?

Accepted Answer

Separation of homologous chromosome pairs

Answer

DNA replication

Answer

Separation of sister chromatids

Answer

Cytokinesis

Question 2

During which specific phase of meiosis does crossing over between homologous chromosomes occur?

Accepted Answer

Prophase I

Answer

Prophase II

Answer

Anaphase I

Answer

Metaphase I

Question 3

Which statement correctly distinguishes a diploid (2n) cell from a haploid (n) cell?

Accepted Answer

Diploid cells contain two complete sets of homologous chromosomes

Answer

Diploid cells have half the DNA of haploid cells

Answer

Haploid cells contain two copies of each chromosome

Answer

Haploid cells are produced only by mitosis

Answer

23

Answer

92

Answer

46, derived from 92 during anaphase
