FIG. 2.

Clone-sharing relationships among six household members at each of six sampling points and overall. A colored line indicates detection of the corresponding clone (see the color code key) in both individuals connected by the line, either concurrently at the same sampling point (top and bottom small boxes for sampling points 1 to 6) or at any time during the study (center large box). F, father; M, mother; S, son; D₁, daughter 1; D₂, daughter 2. Results for samplings 1 to 3 were reported previously (6). Daughters were redesignated here according to age (1 = older, 2 = younger, the reverse of the previously used designations [6]).
