\title{Genotype frequencies for 225 SNPs on chromosome 1 of the CHB population.}
\description{
   The dataframe contains the genotype frequencies in generic notation,
   AA, AB and BB the first 225 polymorphic SNPs without missing data on
   chromosome 1 of the Han Chinese in Beijing. The data are compiled
   from the HapMap project, phase 3.2, containing genotype information
   of 84 individuals.
