Figure 4

Avuncular relationships among schistosome miracidia. Diamonds indicate schistosomes, with those surrounded by a gray box indicating an adult mating pair, and those surrounded by a dashed box indicating miracidia sibling clutches. Chromosomes within diamonds are colored to indicate different haplotype combinations that could be inherited from parents. The arrow points to a sibling of a miracidia clutch collected from Host 1 that became a parent of another sibling clutch collected from Host 2. This worm is the link that creates the depicted avuncular relationship between the offspring of schistosomes within Host 1 and Host 2.
