Table 2 includes the most common haplotypes of the Rh system and their frequencies within various ethnic groups. (Haplotype: a set of genes inherited together from a single parent.)
Note that d represents the absence or lack of the D gene/antigen and continues to be used as a placeholder in the Fisher-Race terminology.
