I had to read a list of relationships and construct a pedigree chart, and I made this. I'm fairly certain it's correct: http://i17.photobucket.com/albums/b66/Jimafu/pedigree.png
First, I am supposed to identify the inheritance pattern. I believe it is X-linked Dominant, is this correct?
I also had a couple questions regarding conventions for drawing pedigrees. Both members of generation I are dead, however I have no example in my book showing slashes through Gen I. No other members are deceased, is it correct to construct this way, with slashes through Gen I? Also, my book tells me to put members of the same generation numbered from left to right, based on age. This is fine for siblings, but what about the spouses of siblings? The information I constructed my pedigree from makes no mention of their ages, and even if it did, the spouse may be older or younger than his betrothed's siblings, meaning he should technically be numbered higher or lower than the nearest adjacent sibling, and also placed spatially on the other side of that sibling, right? It makes sense, but could be very confusing to draw and read...
Just to clarify in case this is not a common convention, the darker blue are affected individuals and the lighter blue are non-affected.
