Presentation transcript:

Mitosis vs. Meiosis

Definition Mitosis Cell Division (Nuclear Division) Meiosis Reduction Division

Mitosis 1 Meiosis 2 # of Divisions 2N (46) DNA Doubles - 92 N N (23)

Type of Cells it Takes Place In Mitosis Somatic (body) cells – skin, digestive tract, mouth, etc. Meiosis Gametes (sex cells) – sperm & egg

Haploid or Diploid Mitosis Diploid (2N) – 2 sets of DNA Meiosis Haploid (1N or N) – 1 set of DNA

# of Daughter Cells Produced Mitosis 2 genetically identical daughter cells Meiosis 4 genetically different gametes (sex cells) female: 1 egg/ 3 polar bodies male: 4 sperm

Type of Reproduction Mitosis Asexual Reproduction (when DNA is contributed by 1 parent) Meiosis Sexual Reproduction (when DNA is contributed by 2 parents)
