Human genetics major concepts

The pattern of DNA sequence variation among humans is greater within populations than between populations. Population genetics theory suggests that rare variants are more likely to be recently derived as compared to common variants and are, therefore, more hkely to be population-specific. This is in concordance with the observation that the majority of human genetic variation occurs among individuals of local populations. Nevertheless, the concept that there is one predominant or wild-type aUele and various rare or mutant forms could not be proved. Instead, there...
