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 http://www.ba-education.com/dna/mitosis.jpg
Meiosis: FYI • Occurs when a cell divides to create reproductive cells • Nucleus divides to create four nuclei http://www.bio.georgiasouthern.edu/bio-home/harvey/lect/images/meiosis.gif
How are Mitosis and Meiosis Different? Mitosis 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 • Produces body cells • Cells used for growth and repair • Produces 2 daughter cells • Daughter cells are identical • Daughters have 2 sets of chromosomes
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 http://www.google.com/imgres?q=cell+division+phas es&um=1&hl=en&client
