Question

There are three genes - A, B, C - on the same chromosome. You have been studying gene A and know that the distance between A and B is 5 m.u. (map units), and the distance between A and C is 3 m.u. Based on the information you have, above, what are potential arrangements of all three genes on the chromosome? You can choose more than one. Note: answers give the genes and map units between them, in order. For example if we had: S--10mu--N--3mu--T that means the genes are in the order SNT, and there are 10 map units between S and N, and 3 map units between N and T. Select one or more: I a. A--3mu--C-- 2mu--B b. B--5mu--A--3mu-- a c. A--2mu--B--3mu-- d. A--3mu--C--5mu--B

Answer 1

a. A--3mu--C--2mu--B

The potential arrangement of the genes A,B and C is ACB, The distance between genes A and C is 3 mu and the distance between A and B is 5 mu.
