Details

Under various scenarios it is useful to know which people in a pedigree belong to the same maternal lines. This function first turns a pedigree into a graph where adjacency is defined by mother-child relationships. Subsequently, the weakly connected components algorithm finds all the separate maternal lines and gives them an ID variable.
