Was confused why immdediate family cant donate blood, had to google it. XD and it is true. Parents to child or vice versa (siblings, grandparents) are incompatible blood donors. Cousins or strangers have better chance of compatibility. Guess this is also the logic to defects in inbreeding. #themoreyouknow
