2. Passing on the Genes $100 Question Although gene shuffling adds variation to a population, this remains the source of new alleles in a population BACK TO GAME ANSWER

3. Passing on the Genes $200 Question This tends to reduce differences between populations due to the loss or gain of alleles when fertile individuals move into or out of a population: BACK TO GAME ANSWER

4. Passing on the Genes $300 Question The resulting differences in a gene pool that is significantly different when compared to the original population may be due to this type of genetic drift. BACK TO GAME ANSWER

5. Passing on the Genes $400 Question The process in which inherited traits are passed down from one generation to the next due to the fitness of the parent resulting in survival and reproduction is called this BACK TO GAME ANSWER

6. Passing on the Genes $500 Question This type of selection for mates occurs between the same sex while the other type of selection occurs between the male and female of that species. BACK TO GAME ANSWER

7. It’s In the Balance $100 Question The parts of the Hardy-Weinberg equation each refer to specific allele combination. In the correct order, name the part of the equation that is homozygous dominant, heterozygous, homozygous recessive BACK TO GAME ANSWER

8. It’s in the Balance $200 Question Natural selection of polygenic traits can occur in several ways. Which type of selection favors individuals at the middle of the distribution curve? BACK TO GAME ANSWER

9. It’s In the Balance $300 Question ___________ selection favors individuals at one end of the continuim of the distribution curve, while ________selection favors individuals at either end of the distribution curve BACK TO GAME ANSWER

10. It’s in the Balance $400 Question An organism that displays an adaptation that is advantageous for survival and yet that adaptation also has significant drawbacks is called this BACK TO GAME ANSWER

11. It’s in the Balance $500 Question Some individuals possess a dominant and a recessive allele for a trait that confers survival to them under certain circumstances. This is known as the: BACK TO GAME ANSWER

12. The Main Players $100 Question This scientist proposed that geologic forces change the surface of the earth and continue to occur today BACK TO GAME ANSWER

13. The Main Players $200 Question Proposed the organisms produce more offspring than the environment can support which leads to competition for resources. His proposal was specifically addressing human population BACK TO GAME ANSWER

14. The Main Players $300 Question Proposed that acquired traits could be passed to offspring BACK TO GAME ANSWER

15. The Main Players $400 Question Proposed a mechanism for determining genetic equilibrium in a population BACK TO GAME ANSWER

16. The Main Players $500 Question Proposed the theory of evolution by natural selection BACK TO GAME ANSWER

17. Everchanging $100 A group of individuals of the same species that live together in the same area and produce fertile offspring is considered to be this

18. Everchanging $200 When allele frequencies change in a population over a period of several generations is termed

19. Everchanging $300 The major source of new alleles is first and foremost this.

20. Everchanging $400 Some species may share similar body structures with other species, but use those structures in different ways. Because they share the same developmental process from embryonic tissue and show evidence of a shared common ancestor, they are called _______________ ___________.

21. Everchanging $500 Occasionally, a small group of individuals will become isolated from the original population and over time the allele frequencies within their respective gene pools will differ significantly. This type of genetic drift is ….

22. Calculations $100 The frequency of p and q always add to this number

23. Calculations $200 If the allele frequency of q is.28, what is the frequency of p?

24. Calculations The number of individuals in a population expressing a certain recessive trait is 13/100. What is the value of p?

25. Calculations $400 If the allele frequency of p is.38 and the allele frequency of q is.62, then what percent are heterozygous?

26. Calculations $500 The percent of individuals that express a recessive trait is 22%. How many individuals would be heterozygous in a population of 500?
