Chapter 8-3: Meiosis

The cells produced via meiosis are called:

• sex cells
• somatic cells
• body cells
• skin cells

Unlike mitosis, meiosis in male mammals results in the formation of

• one haploid gamete
• three diploid gametes
• four diploid gametes
• four haploid gametes

If the Diploid number of Carrots is 18, the haploid number is

• 18
• 9
• 27
• 36

If a body cell in a butterfly contains 24 chromosomes, a butterfly egg would contain

• 3
• 6
• 12
• 24

The chromosomes that pair up during meiosis, are called __________ chromosomes.  

• homozygous 
• asexual
• homologous
• genes

Identify the phase.

• Metaphase I
• Metaphase II
• Prophase I
• Anaphase II

Name the growth phase of the cell cycle for both Mitosis and Meiosis.

• metaphase
• telophase
• interphase
• anaophase

• 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
