Biology

As you showed on the last exam, an experiment at U of Arkansas acouple of years ago showed that the genes for CHF and RA are linkedby a distance of 10.2 cM in pigs. In order to test the linkagerelationship obtained by the U of Arkansas team, a U of Missouribiology team repeated the experiment making exactly the same cross,but using independently obtained pigs.

Healthy pigs: 255

CHF: 40

RA: 44

Both CHF & RA: 261

Total: 600

Conduct a chi2 test to ascertain if there is sufficient groundsfor the Missouri team to reject the Arkansas linkage value. Hint:For your expected values, use the linkage estimate provided by theArkansas researchers to calculate what the Missouri team would haveexpected in their experiment. Be sure to show how you calculatedyour X2 value, your d.f., p-value, and conclusion from your test.For expected values use to 1 decimal, for X2 values use to 2decimals. If you reject the Arkansas hypothesis, propose analternative explanation
