no whole chromosomes?
Thats what my grandfathers comparison to 3 of his grandchildren looks like. Notice the only intact chromosome he shares is chromosome 21 with my maternal half brother.
Purple/dark blue is my maternal half brother
Green is my maternal half sister
Light blue is me.
Also, notice that on chromosome 17 is there no sharing at all for an entire chromosome for two of the grandchildren. My maternal half sister and maternal half brother both inherited a whole chromosome 17 from my maternal grandmother. My maternal half brother also inherited an intact chromosome 8, and chromosome 13 from our maternal grandmother.
