A researcher is interested in whether a disease gene is linked to an RFLP marker. A cross is made between pure breeding blind cavefish and pure breeding sighted cavefish. The lines are pure breeding. The resulting RFLP markers of the F1 offspring and the F2 (from an F1XF1 cross) offspring are shown. Blind cavefish X P Sighted cavefish - F1 Sighted cavefish F2 Sighted cavefish

Question
![A researcher is interested in whether a disease gene is linked to an RFLP marker. A cross is made between
pure breeding blind cavefish and pure breeding sighted cavefish. The lines are pure breeding. The resulting
RFLP markers of the F1 offspring and the F2 (from an F1XF1 cross) offspring are shown.

F2
A. If the disease gene is 10 m.u. from the RFLP marker, what proportion of the F2 will have the gel
pattern shown above AND be blind? Show your work
B. If the disease gene is 10 mu. from the RFLP marker, what proportion of the F2 will have the gel
pattern above AND NOT be blind? Show your work
