SCIENCE JEOPARDY REVIEW Populations and Ecosystems kit Name: Hour: Definitions: 1. The passing of traits from parent to offspring. _____________________ 2. A chart that shows all of the possible combinations of alleles that can result from a genetic cross. _____________________ 3. When there are 2 identical alleles for a trait. _________________ 4. The scientific study of heredity. ______________________ 5. The actual physical appearance of an organism, its visible traits. _____________________ 6. An organism's genetic makeup, the combination of alleles that an organism has. _________________________ 7. An allele whose trait always is seen in the organism when the allele is present in either of the two gene locations. __________________________ 8. A genotype that has 2 different alleles for a gene. ________________________ 9. An allele whose trait is covered up whenever the dominant allele is present. ______________________ 10. The Father of Modern Genetics is named ________________________________ 11. It means non-living or never having lived. _____________ 12. The percentage of water on our planet that is stored in oceans __________ 13. ____________– the range of expression shown in a trait within a population that allows the population to survive even if the environment changes. 14. A system of interacting organisms and abiotic factors in a specified area. ______________________ 15. The two alleles on a paired set of chromosomes form a _______________. 16. All of the organisms of one kind that are in a specified area at one time are called a __________________. 17. The theoretical unlimited growth of a population over time. (The population numbers if there were no limiting factors.) is called ___________________ ___________________. Sexual vs. Asexual Reproduction 1. Which has 2 parents to create the new organism? ____________________ 2. Which only has 1 parent to create the new organism? _______________ 3. Genes are carried from parents to their offspring on _________________________. 4. The name of the cell created for the offspring during reproduction is called a ___________ _________. 5. When the offspring is not identical to the parent due to combining different genes, you have noticed what type of reproduction? ____________________ 6. Four types of asexual reproduction: _________________, __________________, _______________, __________________. 7. Name one of the examples from notes for runners : ___________________ 8. Name one of the examples from notes for fission : ___________________ Punnett Squares 1. Label the phenotype & genotype of Gg if green is dominant _______________________ 2. Label the phenotype& genotype of GG, if Green is dominant ______________________ 3. Label the phenotype & genotype of gg, if green is dominant _______________________ 4. Draw the punnett square for the pairing of these ♀ two parents, Aa x Aa (average arches are dominant) ♂ 5. Draw the punnett squares for the pairing of these two parents (tall is dominant) that are dogwood trees. P = TT x tt & LABEL the offspring’s phenotype ratio ♀ ♂ tall : short. 7. CHOOSE 2 traits below and show punnett squares of crossing and possible offspring. XX XY Genetic Code Genetic Code HH Ee ee TT tt Ff Hh FF Dominants: H= curly hair E= free earlobes T= thick lips F= freckles ♀ ♂ P = ___ X ___ ♀ ♂ P = ____ X ___ Energy and water 1. All energy on Earth begins with energy coming from the _________ to the plant. 2. What are the products of photosynthesis? ___________________________________ 3. What are the reactants of photosynthesis? ___________________________________ 4. Name 3 things we need to know to calculate reproductive potential? _________________________________________________________________________ ________________________________________________________________________ 5. Place the following list in the order they go to show how energy would flow in the ecosystem: ___decomposer ___producer ____sun ___consumer 6. Show arrows to represent the energy flow connecting the list in # 5. 7. _______________ is the decomposer that is most often present in any environment. 8. What is the 10% rule of energy transfer? 9. Organisms use energy for _____ life ____________. 10. Freshwater makes up _____ than _____ of Earth’s water. 11. What is different about a wooly mammoth and an elephant? ______________________________________________________________________. 12. What is a benefit to having a water treatment plant? _______________________________ _____________________________________________________________________. Extra Credit For test (3 points) Other than movement, what are the three other categories of energy use for an organism?_________________________________________________________
