Genetically speaking, your mother and father both supplied 50% of the DNA to make you. However, certain genes will be recessive, so theoretically, I'm guessing you could take after one parent more than an other, but both equally so. As for siblings, they will also be made of 50% of each parent's DNA, so on one level, they're closer than your parents are - all siblings are made up of the same amount of their parent's DNA!
On a social level, despite the swathes cut through gender inequalites over the past 100 years or so, legally we generally follow a Patrilineal line - that is one where the father's name is taken, and lineage tends to be traced through the male line. Other cultures have matrilineal lines, and others have lines which would take a book to discuss... Hope this helps..!
