wtf man? take a biology class or something.
Sperm or any reproductive cell is whats called a Haploid, this means it only has half of your chromosomes in it. You normally have 46 chromosomes (ill talk about abonrmalities later). Now normal cells divide they duplicated the chromosomes, when sex cells devide they seperate the chromosomes. So what once was a 46 is now 23. Each sperm cell has 23 chromosomes. But what is different, is that each sperm cell has a different combination of those chromosomes. So one sperm cell might have the chromosome pattern for blue eyes, blond hair, fair skin. Another sperm cell will have the pattern for red hair, brown eyes, and dark skin. Its all about recessive and dominate genese.
If every sperm cell was identical, then every brother would look exactly like his other brother, every sister would look exactly like her other sister. There would be no difference in people who come form the same parents because they would all have the exact same genetic code.
Its pretty interesting to actually find out how rare it is that you exist. You were one special sperm out of thousands that made it, any other sperm and you would not be who you are today. You might have different hair, eyes, skin, height, anything.
But this thread is all wrong, its not about surviving the odds, either way you were going to be here, but being the way you are, that is a one in a million chance.
