They give a superficial impression of difference (which in some cases does not have a clear genetic basis), relative to overwhelming similarity in functional regions of DNA (nyti.ms/3CxBxcj, nature.com/articles/ng1456). Noncoding regions on the other hand tend to yield a reasonable historical record of population differentiation, because they are not functionally constrained, and mutations in regions without functions are therefore more likely to be passed on. | |
