9.) Write the phenotype symbols in the right-hand column. The first one has been done for you.
10.) Next to that, label all fly categories as parental (NCOs), SCOs, and DCOs. One has been done
for you.
11.) After each SCO/DCO label, write which gene got “unlinked” in these offspring.
12.) Put these three genes into a genetic map in the proper order.
13.) Calculate the genetic distance between the genes and label the map with these distances.
14.) Calculate the cross-over interference
15.) Return to questions #1-6 above. For question 6, you gave your opinion, but what is the more
scientifically appropriate way to determine if these two genes are linked on the same
chromosome using the data given?
16.) Perform the appropriate statistical test on the data provided in #5 above and give the value that
you calculate for this test. What does this value tell you, according to the chart in chapter 4?
