Damages your kidneys preventing them from cleaning up blood as well as they should. This damage can cause wastes to build up in your body and lead to health problems such as heart disease, anemia and bone disease.
The right answer is: it affects the excretory function of the organism.
Take the example of chronic kidney disease (CKD).
Each minute, about 1 liter of blood is filtered by the kidney (1/5 of the amount pumped by the heart). Chronic kidney disease (or chronic renal failure) is a serious condition that causes a gradual and irreversible deterioration of the kidneys' ability to filter blood and excrete certain hormones. The excess of water and the waste metabolism products pass less into the urine and accumulate in the body.
The DNA of the baby shares the DNA of both father and mother, and hence a cross link between an O type mother (Taylor) and an AB type father (Tyler) will produce children with blood groups A and B. It will be impossible to give birth to a child with blood group O.
