1. Review Game Work with your table group to complete each question the group with the most points at the end of the game wins

2. Each parent passes on how many chromosomes? 23

3. How many chromosomes pairs do humans have? 23

4. A single celled organism reproduces by dividing itself into two genetically identical offspring. What type of asexual reproduction is the cell using? Binary fission

5. DNA from two parents is combined to make an offspring. What type of reproduction is taking place? Sexual Reproduction

6. Create a T-Chart identifying the two major differences between sexual and asexual reproduction. Sexual Reproduction: 2 parents, genetically different offspring Asexual Reproduction: 1 parent, genetically identical offspring

7. List two advantages of asexual reproduction Produce many offspring, Do not need a mate, less energy

8. List two advantages of sexual reproduction Genetic variation, Greater ability to adapt to surroundings

9. List the major disadvantage of asexual reproduction No genetic diversity

10. List 2 disadvantages of sexual reproduction More energy, large chance of mutation

11. Tall (T) is dominant to Short (t) in pea plants. What percentage of offspring would be heterozygous when a homozygous tall plant is crossed with a homozygous short plant? 100%

12. Tall (T) is dominant to Short (t) in pea plants. What percentage of offspring would be homozygous short when crossing two heterozygous tall plants? 25%

13. Tall (T) is dominant to Short (t) in pea plants. A cross was made between two pea plants, which resulted in the following offspring. 77 tall plants 23 short plants What is the most likely genotype combination of the parent plants? TtxTt

14. Demetrius looks very similar to his father. Did he receive more genetic information from his father than from his mother? Support your decision. No, he received 23 from each parent, his father may have passed on more dominant alleles than his mother.

15. Use the results from your quiz to give a complete set of traits for the offspring.

16. The shapes below represent two different species: A and B. Both species live in the same small puddle and compete for the same food source. Which species, A or B, reproduces asexually? What observation(s) support your answer? A, they are all exactly the same

17. The shapes below represent two different species: A and B. Both species live in the same small puddle and compete for the same food source. The puddle floods and the food source washes away to another part of the puddle. Describe one advantage species B has in this environment to allow survival and reproduction for several generations? Some of them have long tails which may allow them to move to the new food location.
