This data set gives the frequencies of haplotypes of mitochondrial DNA restriction data in ten populations all over the world.
It gives also distances among the haplotypes.
humDNAm is a list of 3 components.
is an object of class
dist with 56 haplotypes.
These distances are computed by counting the number of differences in restriction sites between two haplotypes.
is a data frame with 56 haplotypes, 10 abundance variables (populations). These variables give the haplotype abundance in a given population.
is a data frame with 10 populations, 1 variable (classification). This variable gives the name of the continent in which a given population is located.
