1. Reproduction and Genetics
CHapter 6+7

2. Inside the Cell
Chromosomes - tightly wound DNA

3. Mitosis and Meiosis
Mitosis - creates identical copies, can be used for growth, repair, and reproduction
Meiosis - creates sperm and egg (1/2 the number of chromosomes), only used for reproduction

4. Types of reproduction
Sexual Reproduction - union of gametes through meiosis (sperm and egg meet)
- half the number of chromosomes are found in each gamete
- creates four new cells
Asexual Reproduction - identical copies of cell through mitosis
- identical number of chromosomes in both parent and offspring
- creates two new cells

5. Sexual Reproduction
Meiosis - makes sperm and egg (each have 1/2 the number of chromosomes)
Fertilization - sperm and egg meet (together they provide the full set of chromosomes)
Differentiation - the cell rapidly grows due to mitosis

6. Which has more variation?
SEXUAL REPRODUCTION!
Random assortment of genes from mom and dad

7. Plant Reproduction Occurs in the flower:
Pistil - female reproductive organs
Stamen - male reproductive organs

8. Seed

9. cancer
Rapid Mitotic division

10. punnet Squares Dominant - trait shows up most frequently
Recessive - trait shows up less frequently
Phenotype - the trait that shows
Genotype - the gene that shows

11. genetic Engineering Manipulating genes to create modified organisms
Cloning - taking the DNA from one organism and placing it into the egg cell of a different organism to create an identical organism.

12. Evolution Gradual change in an organism over time
Adaptation - traits allow you to survive in your environment
Extinction - this occurs when you cannot survive in your environment
