1. Reproduction: Mitosis and Meiosis
EOC Review

2. Parent & Daughter Cells
Cells come from pre-existing cells
Parent cells divide to produce daughter cells

3. Chromosomes Store genetic information, made of DNA and protein
Karyotype: shows normal number of chromosomes in each cell

4. Questions How many chromosomes are in the karyotype?
How many pairs of chromosomes?
Is subject male or female?
Which are homologous?

5. Comparing Mitosis & Meiosis
Purpose of Process
Number of Daughter Cells Produced
Number of Chromosomes in Parent Cell (Human)
Daughter Cells Diploid (2n)
Or Haploid (n)?
Daughter Cells Genetically Identical to Parent?
Daughter Cells Genetically Identical to Each Other?

6. Types of Reproduction
Sexual: union of 2 germ cells (gametes) by fertilization
50% of DNA from each parent
Asexual: reproduction that does not involve fusion of gametes
Progeny identical to parents

7. Sexual Reproduction Advantages: genetic recombination
Disadvantages: energy and effort

8. Asexual Reproduction Cloning: process of producing identical organisms
Budding: method of sexual reproduction in which juvenile grows out of adult
Binary fission: used by bacteria, cell is split into two identical cells

9. Asexual Reproduction: Budding

10. Asexual Reproduction: Binary fission

11. 1. Which of these is not a difference between mitosis and meiosis?
Mitosis results in two cells; meiosis results in four.
Mitosis is a form of asexual reproduction; meiosis is a form of sexual reproduction.
Mitosis produces cells with a full set of chromosomes; meiosis produces cells with a half set of chromosomes.
Mitosis occurs only in multicellular organisms such as paramecia; meiosis occurs only in multicellular organisms such as humans.
