Figure 1.

Physical chromosome length is associated with the number of breakpoints on chromosomes, but not the translocation frequency. (a) Scatterplot comparing the number of breakpoints to the physical length of each chromosome. Spearman’s correlation coefficient was used to determine if there is a relationship between the two variables, r = Spearman’s correlation coefficient, p = numerical representation that the result was seen by chance, n = number of chromosomes considered in the analysis. (b) Scatterplot comparing the translocation frequency and physical length of each chromosome. Spearman’s correlation coefficient was used as described above.
