Chi Square Review 2 2 ( o e) 1. Formulas: Chi Square o = observed individuals with observed genotype e e = expected individuals with observed genotype Degrees of freedom equals the number of distinct possible outcomes minus one Degrees of Freedom p 1 2 3 4 5 6 7 8 0.05 3.84 5.99 7.82 9.49 11.07 12.59 14.07 15.51 0.01 6.64 9.32 11.34 13.28 15.09 16.81 18.48 20.09 Example problem: Wisconsin Fast Plants have two very distinctive visible traits (stems and leaves). Each plant will either have a purple (P) or green (p) stem and also have either have green (G) or yellow (g) leaves. Suppose that we cross a dihybrid heterozygous plant with another plant that is homozygous purple stem and heterozygous for the leaf trait. Make a Punnett square to figure out the expected ratios for the phenotypes of the offspring. Surface Area to Volume Ratio 1) Cells throughout the world have variable shapes and sizes. Because of this, and because structure is designed around function, certain shapes are optimal for certain processes. Analyze the following cells (units not to scale), and determine the following Cell 1 (spherical) where the radius is 3 mm
Cell 2 (flat and rectangular) where the height is 0.5mm, length is 4mm, width is 2mm a. What is the surface area to volume ratio of both cells? How to calculate Surface Area? Cell 1 Surface area How to calculate Volume? Volume Surface area to Volume Ratio Cell 2 b. Conclusion: Compare the ratios and explain why one cell would be more efficient than another. c. Are you made of lots of large cells or lots of small cells? Why? How do you actually grow in height?
