You will be using a chi square test to either refute or support the assumption that the
genes for corn kernel colour and texture are independently assorting or linked.
1. Generate a null hypothesis. A null hypothesis is a simple, specific
assumption about the results before the results are known.
2.Perform a chi square test on the data assigned to you. Report the
equation used, the chi square value, the degrees of freedom, and the resulting pvalue.
3.Based on your assigned data, is the null hypothesis accepted or
rejected? Does your chi square analysis of the corn data indicate that the genes
for colour and texture are found on the same chromosome (linked) or on different
chromosomes (independent)? Explain.
4. If you consider the class data as a whole, would the result be the
same? Provide evidence to support your answer.
