comment “Same” DNA vs genes
Note that siblings sharing half their genes only reflects the approximation that they get one of each pair from their father and one from their mother. If the father and mother have the same genes at that location, the siblings will match 100%

comment Strictly from a biological perspective, what is the functional expectation of a human being
Although "What is the purpose of human feet" and "What is the purpose of human existence" have the same word pattern, they are quite distinct English sentences, even before the biology question. The first can be answered with what good feet do for people. The second asks what good people do for something (what?) I would -1 this if I had the rep on this site (I have lots on math) Looks like a troll to me. Biology and purpose rarely belong in the same sentence.
