Multiple Mates

• If an individual has more than 2 mates, it is not possible to draw them side-by-side.

  
  
  
  

• Solution: Use alias to convert multiple matings into ``normal'' matings
  • Suppose x mate y1, x mate y2, and x mate y3
  • Introduce aliases x1, x2, and x3
  • Replace x mate y1 by x1 mate y1, x mate y2 by x2 mate y2, and x mate y3 by x3 mate y3
  • Replace links to x from parental unit of x by links to x1, x2, and x3

  
  
  
  

• An example pedigree diagram derived from our example bad diagram by (i) the multiple matings of ``6'' are converted into two single matings, one of which is consanguineous with ``13'', and (ii) the consanguineous mating is converted into a normal one.
