Will a blood transfusion alter one's genetic make-up?


Answer:
No. The blood breaks down fairly quickly anyway, and is only a temporary measure to give you enough time for your body to create it's own.
No, you don't turn into half apple half human after eating an apple do you? We eat DNA in food all the time. Nothing to worry about.
Red blood cells do not contain any DNA material, and therefore cannot replicate themselvles. Once they die, they have to be produced by hematopoietic stem cells, or replaced with another transfusion. So NO, it will not alter your genetic makeup.
No. Chemicals in blood is not strong enough to create such an effect and they are usually broken down after a week or two. Process such as radiation might cause an alteration to your genetic make-up, which most probably results in cancer
Of course not. Your genetic makeup is in every cell in your body, not just your blood.
Certainly not. Blood transfusion will not alter one's genetic make-up. However, as recently as World War II, the United States kept black and white blood separate because of just that fear.On 16 January 1942 the Navy announced that "in deference to the wishes of those for whom the plasma is being provided, the blood will be processed separately so that those receiving transfusions may be given blood of their own race." Three days later the Chief of the Bureau of Medicine, who was also the President's personal physician, told the Secretary of the Navy, " It is my opinion that at this time we cannot afford to open up a subject such as mixing blood or plasma regardless of the theoretical fact that there is no chemical difference in human blood." See Memo, Rear Adm Ross T. Mclntire for SecNav, 19 Jan 42, GenRecsNav. See also Florence Murray, ed., Negro Handbook, 1946-1947 (New York: A. A. Wyn, 1948), pp. 373-74. For effect of segregated blood banks on black morale, see Mary A. Morton, "The Federal Government and Negro Morale, " Journal of Negro,Education (Summer 1943): 452, 455-56.
