Meiosis Phase 1

How many daughter cells are made at the end of Meiosis l?

• 2

• 3

• 4

• 6

Crossing over is the process of...

• chromosomes separating during Anaphase

• tiny pieces being exchanged on two sister chromatids

• chromatids lining up in the middle of the cell during Metaphase

During Prophase l of MEISOSI...

• the cell is split in two

• chromosomes line up in the middle of the cell

• crossing over occurs between two chromosomes

_____________ is the type of cell division that makes gametes.

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

• anaphase 1

• prophase 1

• prophase 2

• telophase 1

The result of meiosis is:

• two diploid cells

• two haploid cells

• four diploid cells

• four haploid cells

Before a cell can divide, what must happen?

• Nothing, it is always ready to divide

• The number of chromosomes must be cut in half

• The number of chromosomes must double

• The number of chromosomes must triple.
