Genealogy of the Easter Island individuals included in our molecular genetic studies of the serum samples from 1971. The numbers of the individuals are the same as used in Lie et al. [22], whereas the haplotype designations are slightly different. The most probable HLA haplotypes (table 1) are listed under each genotyped individual. The two haplotypes carrying Amerindian HLA alleles, haplotypes a and b, are coloured red and yellow, respectively. Haplotypes carrying European (i.e. haplotype c) or Polynesian HLA alleles are coloured grey. Open circles or squares mean that the individuals have not been investigated.
