Fig. 1From: Breast milk and in utero transmission of HIV-1 select for envelope variants with unique molecular signaturesMosaic plots showing groupings by subject (maternal or infant), transmission mode, and transmission pair ID number for the 647 infant- and maternal-derived envelope clones obtained in this study. The number of envelope variants represented within each group is indicated inside each tile. IUT, in utero transmission; BMT, breast milk transmission; IND, indeterminate transmission mode. Twenty-one transmission pairs were infected with HIV-1 subtype C, while one pair (Pair 8, shown in green) was infected with subtype GBack to article page
