LT: I will be able to explain the stages of meiosis and how they are different from mitosis.

Know: What do you think happens to chromosomes during meiosis?

Mitosis: Review

• Occurs when a single cell divides, and two identical daughter cells are made– Daughter cells

contain the same number of chromosomes and genetic information as the parent cell

Meiosis: FYI

• Occurs when a cell divides to create reproductive cells– Nucleus divides to

create four nuclei

How are Mitosis and Meiosis Different?

Mitosis• Produces body cells

– Cells used for growth and repair

• Produces 2 daughter cells – Daughter cells are identical– Daughters have 2 sets of

chromosomes

Meiosis• Produces sex cells

– Cells used for sexual reproduction

• Produces 4 daughter cells– Daughter cells have ½ of their

genes from parent cell– Daughter cells can get only 1

part of each chromosome

How are Mitosis and Meiosis the same?

• Have cell division– A parent cell divides,

and creates daughter cells

• Have phases of cell division

• Involve chromosome replication
