1. In asexual reproduction, are the offspring different or the same as the parent? Answer: SAME! They are clones and genetically identical.

2. Which type of asexual reproduction is shown? Answer: Budding

3. Which type of sexual reproduction is illustrated below? Answer: External fertilization

4. Which type of sexual reproduction is illustrated below? Answer: Binary Fission

5. Do all the cells on your body contain the same DNA (genetic information)? Yes/No? YES!!! You started off as just ONE cell that went through many stages of mitosis. All of your cells have the SAME DNA.

6. Why are there so many different types of reproduction? There are ADVANTAGES and DISADVANTAGES to each type!

7. Asexual Reproduction ADVANTAGES 1)Don’t have to find a mate 2)Very quick 3)Produces a lot of offspring if the conditions are right 4)Offspring have the same genetics Asexual Reproduction: 1 parent produces offspring that are genetically identical to themselves

8. Asexual Reproduction DISADVANTAGE All of the offspring are exactly the same as the parents. They have the same DNA and mix of traits. Why is this bad? If the parent has a gene that causes a particular disease, the offspring will also have the gene that causes that disease. Also, offspring have less of a chance of survival and adaptability if the environment changes.

9. SEXUAL REPRODUCTION. = 2 parents produce offspring that are a combination of their genetic information; they are genetically different from each other and from their parents. Most animals have separate male and female sexes. Male produces sperm Female produces eggs Fertilization: union of egg and sperm

10. Animal Reproductive Organs Animals often have gonads, organs that produce eggs or sperm. Testes (male) produce sperm. Ovaries (female) produce eggs. 1 egg = 1 cell 1 sperm = 1 cell

11. Gametes = sex cells, such as a sperm or egg Half the amount of genetic information as a regular body cell. If a regular human body cell has 46 chromosomes, how many does a sperm cell have? A human sperm cell has 23 chromosomes.

12. ZYGOTE = the first cell of a new organism that is formed when a sperm and egg unite. Combines the parents genetic information Genetically unique Produced by meiosis and then grows by mitosis.

13. Sexual Reproduction Advantage = GENETIC VARIATION IN OFFSPRING! Offspring from sexual reproduction are a combination of their parents (they have traits from both!) More diversity (differences) in the species means that they are better able to adapt to changes in the environment!

14. Sexual Reproduction Advantage = GENETIC VARIATION IN OFFSPRING! Genetic variation also decreases the likelihood of inheriting bad traits. Diseases, disorders, intolerance to certain conditions

15. Sexual Reproduction Disadvantages 1) Have to find a mate More time spent finding a mate = more time for predators to find you and less time for other things (finding food, seeking shelter) 2) One mate may not be as good as another Have to select the appropriate mate = time + effort
