Meiosis

How many chromosomes are in an egg or sperm cell at the end of Meiosis?

• 23

• 46

• 64

• 32

In what phase is the DNA of the cell replicated or copied?

• Interphase

• Prophase I

• Telophase I

• Metaphase I

Crossing over occurs in what phase of Meiosis?

• Prophase I

• Prophase II

• Metaphase I

• Interphase

Homologous pairs line up in the middle of the cell in what phase of Meiosis?

• Metaphase I

• Metaphase II

• Mitosis

• Prophase II

Genetic information is transferred to homologous pairs during what?

• Cytokinesis

• Crossing over

• Interphase

What phase is in the picture?

• Anaphase I

• Anaphase II

• Telophase I

• Metaphase II

A human body (somatic) cell usually has how many chromosomes?

• 6

• 22

• 4

• 46

If the diploid number of carrots is 18, the haploid number is

• 18

• 9

• 27

• 36

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells

The result of meiosis is:

• two diploid cells
• two haploid cells
• four diploid cells
• four haploid cells
