Rachel Romm Biology 1H P5 Ms. Mackley 13 March 2009 Chi Squared Analysis of Corn Introduction: People use chi-squares to determine the error and chance probability in the data. The error in the data collected can be statistically significant if the percent due to chance is less than ten percent or more than ninety percent due to other things such as error. To find the chi-squared value, the given equation is X 2 = Σ ((O – E) 2 / E) or chi-squared equals observed data minus expected squared divided by expected plus the answer for the allele. Data: Data Table 1: Observed Corn Kernel Color Data Table 2: Expected Corn Kernel Color Kernel Color Number Of Purple (dominant) 307 Yellow (recessive) 308 Since the observed ratio was 1:1, there was a back cross. A member of the F 1 generation mated with one of the purebred P generation plants. Therefore, the P generation parent was purebred purple and in order for the offspring to be 1:1, the F
