Multiple Choice

When does "crossing over" of genes occur during meiosis?

• Prophase I

• Metaphase I

• Anaphase I

• Telophase I

Multiple Choice

During meiosis, if an organism has 10 chromosomes, how many will be in each gamete (egg or sperm cells) of the new daughter cells?

• 10

• 8

• 5

• 2

Multiple Choice

True or False: Crossing over only occurs in meiosis.

• True

• False

Multiple Choice

What happens during anaphase?

• Chromosomes/chromatids line up in center

• Nucleus dissolves

• The cell divides

• Chromosomes/chromatids are pulled apart

Multiple Choice

What is a gamete?

• a body cell (ex. skin or heart cell)

• an autosome

• a sex cell (ex. sperm or egg)

• a somatic cell

Multiple Choice

• Telophase I
• Metaphase II
• Telophase II
• Anaphase I

Multiple Choice
