Fig. 4From: Haplotype variation in the ACE gene in global populations, with special reference to India, and an alternative model of evolution of haplotypesProposed recombination events have resulted in different common haplotypes. The putative recombinants (PuR1 and PuR2) represent clades A and B proposed by Keavney et al. (1998), while the putative non–recombinants PuNR1 and PuNR2 represent the clade C. The putative non-recombinants PuNR1, PuNR2, and PuNR3 is the major haplotype in the African populations. The arrow (↕) represents possible mutation events. Numbers within crotchets indicate the haplotype number from Table 2Back to article page
