Meiosis Review

The cells produced via meiosis are called:

• gamete cells

• somatic cells
• body cells
• skin cells

When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, _________________ occurs

• crossing over
• mutagenesis
• hybridization
• fertilization

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

• 3
• 6
• 12
• 24

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

• anaphase 1
• prophase 1
• prophase 2
• telophase 1

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

During meiosis I, what happens? 

• Sister chromatids are split
• Homologous chromosomes are split
• Four cells are created
• None of the other choices are correct

The purpose of meiosis is to form ________ cells.

• body
• gamete

• somatic
• brain

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

• homozygous 
• asexual
• homologous
• genes
• sister chromatids

How many daughter cells are produced at the end of meiosis?

• 1
• 2
• 3
• 4

What phase is represented?

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