Observed value o Expected value e Deviation o e or d

Observed value o Expected value e Deviation o e or d Deviation d d e Smooth Rough Smooth Rough Chi square X d e If you have a ratio of 9 3 3 1 then to calculate the percentage you have to add the total sum of the groups 16 and that is your denominator and then each group is the numerator For example 9 16 is 56 3 16 is 19 3 16 is 19 and 1 16 is 6 which equal 100 12 What is your p value Notes regarding calculating the chi square number Obtain your observed values from Table 5 Calculate your expected e values based on your predicted phenotypic ratio and using the total number of kernels calculated in Table 5 Use your X number to determine your p probability value Use the Chi square table Table 4 to assist you in your calculations 11 What is your degree of freedom value 13 What are your conclusions based on your calculations Based on your experiment state which phenotypes are dominant and which are recessive Are there any significant differences between your observed and expected values and is your hypothesis supported

3 In mice dwarfism is caused by an X linked recessive allele and the pink coat is caused by an autosomal dominant allele Coats are normally brownish Suppose a dwarf brown female from a pure breeding line is crossed with a normal sized pink male from a pure breeding line What are the genotypes of the parental mice Define your own gene and allele symbols What will the predicted phenotypic ratios be in the F1 generation for each sex
