Ribosome RNA genes

Post by jbraves17 » Tue Sep 26, 2006 12:38 am

I'm lost, and hope someone can provide some insight into this for me.

Why wouldn't these types of genes be effiecient in studying/examing populations?

In molecular phylogenetics, the more closely related the groups you want to differentiate are to each other, the more variable the loci you use need to be. So, for closely related groups such as populations of a single species, you need to use loci that are variable enough to possess differences between populations. In general, ribosomal RNA loci are insufficiently variable for populations, but are variable enough to differentiate between species and higher taxa. For populations, you'll need loci that will accumulate mutations at a faster rate than rRNA genes do.
