Question
From a series of two-point crosses, the following map
distances were obtained for the syntenic genes A, B,
C, and D in peas:
B ↔ C 23 m.u.
A ↔ C 15 m.u.
C ↔ D 14 m.u.
A ↔ B 12 m.u.
B ↔ D 11 m.u.
A ↔ D 1 m.u.
Chi-square analysis cannot reject the null hypothesis of no linkage for gene E with any of the
other four genes.
a. Draw a cross scheme that would allow you to
determine the B ↔ C map distance.
b. Diagram the best genetic map that can be assembled from this data set.
c. Explain any inconsistencies or unknown features in
your map.
d. What additional experiments would allow you to
resolve these inconsistencies or ambiguities?
