Changes

More often than not, we expect that the reference genome will include the most common allele, which is also likely to be the ancestral allele. Thus, if C->T mutations are more common than T->C mutations, we expect to see an imbalance of C->T versus T->C changes. Further, when comparing rare and common variants, we expect the imbalance to be stronger for lower frequency variants.
