wait, as far as i understand i was made from the union of a sperm and an
egg cell. however, those are long gone. the DNA is still around, but DNA
is not a cell. what cells in me are older than me? i think i am missing a
genetic point. if i pass on my dna to my child, he or she will have half
my dna but not any of "my" cells, i.e. cells in me right now. or will
s/he? am i wrong?
as for the rest: what do you mean by saying my father's sperm cell was
"selected out" ?
