Organisms that are closely related have a greater similarity in their DNA base sequences.

Not all the DNA of organisms codes for protein. There are more mutations in non-coding DNA than there are in normal DNA. Therefore, closely related species will have a similar number of repeats. 

Short Tandem Repeats (STR's) are regions of non-coding DNA. These STR's can be…
