Sequence states of the 24 PSVs in proximal and distal inter-AD segments within 36 Y chromosomes, organized according to the Y phylogeny. Bases shown in white on black are distal specific, and those in black on white are proximal specific, as defined by the reference sequence (Ref). Names of DNA samples are given on the right; on the left, a simplified version of the Y phylogeny (Y Chromosome Consortium 2002) shows the phylogenetic relationships and haplogroup names of the chromosomes analyzed. Sequences within haplogroup J contain a deletion of 13 bp between PSVs 18 and 19, in both proximal and distal sequences. Case 1, case 2, and YCC26 proximal and distal sequences have been reported previously (respectively, AJ511660-1, AJ511663-4, AJ511666-7; Bosch and Jobling 2003). Sequence positions from 103 to 724 (bottom) give coordinates within the inter-AD segments: The position labeled 103 is equivalent to nucleotide no. 11739 on the plus strand of AC002992 for the proximal HERV, and to nucleotide no. 144340 on the minus strand of AC005820 for the distal HERV.
