Query about human repreduction

    When a woman and a man have sex, the man ejaculates and millions of sperm are shot into the woman.

    One of these millions of sperm will fuse with her egg typically.

    We were all that one sperm and we were all that egg at one point, correct?

    My question, if a DIFFERENT sperm, instead of the one that fertilised the egg had fertilised the egg (say "we" came second), would "we" die with all the other millions of sperm and not exists today? Would someone else be in our place (that other sperm that "beat us"?).

    Or are we really the egg, and the sperm is all identical and carrys identical genetic material?

    I would like answers to these questions as I have been thinking about them for a while. If the case is that the sperm we "were" at one point DIDN'T fertilise the egg and died, and that means we died too, then we are INCREDIBLY lucky to be alive. It would also mean that if our parents had had sex an hour beforehand, we might not have won the race as we would have been in a different position when our father ejactulated us.

    Am I right here?

    differnt sperm carry differnt parts of the genetic code whcih has slight variations so while you and your sibling may look similar you are not identical.

    well since "we" are really a combination of that particular sperm and that particular egg then if that particular sperm never reached that egg it means we never existed as opposed to having died.

    Since having my kids that kind of thinking does my head in...... thinking of all the millions of combinations sperm and egg that there could have been and all the millions of children I could have had :eek:
    I do think I got the best two though :D
