Breakage at fragile sites, such as the Fragile X site, is correlated with having a large number of copies of a 3-base repeat, but is caused by:

You conduct a series of two-point mapping crosses involving five genes, named A through E, located on chromosome III. Given that gene A is at the end of the chromosome, what is the order of these genes along the chromosome, based on the ten percentages of recombinant offspring below as discovered in your experiments? A-B 23.5%,  C-A   9.0%,  C-B 14.5%,  D-C 14.0%,  D-A   9.5%,  D-B 14.0%,  E-B   6.8%, E-A 16.7%,  E-C   7.7%,  E-D   7.2%
