Meiosis Review

In humans, the haploid number of chromosomes is ____.

• 23

• 46

• 69

• 92

Which of the following is the best definition for MEIOSIS?

• the process of two haploid cells uniting

• the counting of chromosomes within a diploid cell

• a two-step process that reduces the number of chromosomes in half such that there is only one copy of all the chromosomes

• the equational division of a cell into two identical copies

True or False? Before cells undergo meiosis they pass through interphase first.

• true

• false

What phase is  shown in the picture?

• anaphase 1
• anaphase 2
• metaphase 1
• telophase 1

The process of crossing over occurs in what phase of meiosis?

• anaphase 1

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids
• condensation and segregation of alleles
