410 C-Fern Group Paper

● Only solid-green? ● Either polka-dot or solid-green? 7. Solid-green sporophytes will produce gametophytes in your plates and in nature that are which one of the following? No explanation needed. ● Only polka-dot? ● Only solid-green? ● Either polka-dot or solid-green? 8. Analyze the class data on gametophytes using chi-square analysis and complete the following table. Carefully read “Statistical Tests for BIOL 410” at the end of the Lab Manual . Indicate a significant chi-square value by appropriately using “*”. Table A Calculation of Χ 2 from class data of gametophytes Phenotype O E d = (O - E) d 2 d 2 /E Solid green Polka dot Total Χ 2 = * Statistically significant (P< 0.05). 9. What are the degrees of freedom for Table A? 10. What is the approximate probability (P) value of your calculated Χ 2 in Table A? [Interpret the chi- square probability table in the Lab Manual . For example, is P between 0.05 and 0.1? Or < 0.005?] 11. What is the hypothesis you are testing in Table A? See “Statistical Tests for BIOL 410.” 12. Is your tested hypothesis in Table A supported or not supported? Explain why by stating the critical value of Χ 2 , comparing your calculated Χ 2 value to the critical value of Χ 2 , and then interpreting the P value. See “Statistical Tests for BIOL 410.” 13. Analyze the class data on sporophytes using chi-square analysis, and complete the following table. Carefully read “Statistical Tests for BIOL 410.” Indicate a significant chi-square value by appropriately using “*”.
