Document Summary
Sum of (observed expected) 2 / expected value for each type of progeny. To determine the probability associated with this chi-square value. Degrees of freedom are number of ways in which the observed classes are free to vary from the expected values. Chi-square of 30. 73 with df of 1 is larger than largest chi-square value which has a probability of 0. 005. Genotypes are not in proportions we would expect if independent assortment. A 0. 05 probability (p) level is the typically accepted cutoff value. Suggest chance is responsible for the deviation seen between expected and observed values. Suggest that chance is not responsible, and a significant difference exists. @ df of 1, 30 is much larger than p value associated for less than 0. 05, so. = high degree of linkage between alleles governing this particular loci. Crossover events occur more or less at random up and down the chromosome.
