Which phase of mitosis is incorrectly paired?

(Chapter 6)

• Telophase - Cell begins to split

What occurs during interphase?

(Chapter 6)

• The cell grows, duplicates DNA and prepares for mitosis.

• The cell grows spindle fibers from the centrioles.

• Chromosomes are pulled to opposite ends of the cell.

• The chromosomes are duplicated and half are given to each daughter cell.

Which phase does this represent?

(Chapter 6)

• Metaphase II

• Anaphase I

• Metaphase I

• Prophase

Based upon the chart, how many chromosomes are in a gamete pigeon cell?

(Chapter 6)

• 20 because gamete cells are haploid

• 80 because gamete cells are diploid

• 40 because gamete cells are haploid
