Friend has a question about blood transfusion's.?


Question:
Say you had a complete blood transfusion (maybe more the once?). Would your DNA still match that of your familys DNA line?

Reason for asking is, one of my friends cousins really likes him (and he likes her), but they are 1st cousins and have read that because of the family bloodline and the DNA being so close if they had a child it would have a high risk of being deformed.

Anyways i told him i would ask, so if you went through a complete blood transfusion (or more then once) would it be the same as the familys still?

Answers:
This is a myth, the part about 1st cousins having deformed babies. The truth is that, although it might be a little weird for most people, there's no more of a risk than anyone else. It's even legal in some places to marry your 1st cousin. So, although they can't get blood transfusions to change your DNA, they can have kids and most likely they won't have 2 heads, 3 eyes or extra limbs.
Your dna will never ever ever ever change no matter what I promise.
