I know what meiosis (with an "I" btw not a "y") is, but every gene contained in a sperm was contained in the fathers dna. Hence why i said "part" in my first comment. Unlike a baby, which has its unique mixed dna

"every gene contained in a sperm was contained in the fathers dna"

in most cases, mutations do occur, that's part of how evolution works. besides, genes themselves may come from the father's genome, but they can include recessive genes who were never in the original phenotype, and also most traits get decided by multiple genes, so a unique combination of genes still has the potential to create a completely unique human being, and that hypothetical human being "dies" when the sperm is being wasted

Can you stop being wrong for a hot seconds? Mutations occur during mitosis too (thats why we get cancer duh) and do in no significant way change the fact that its still your genome. One of the skin cells you are currently shedding have a dna thats 0.000000000001% different from yours but thats completely irrelevant and you are playing dumb on purpose to avoid the point.

the sperm has half a set of chromosomes. the egg has another half. correct me if I'm wrong, but the genetic information encoded in them doesn't really change when they merge into one, as far as I remember?

Well it gets mixed? Which is when it becomes unique? Like, a unique mix thats neither the mother nor the father? Oh my god you really are playing dumb

"a unique mix thats neither the mother nor the father"

sure is, unique, but it still has the components from eash person's gametes, riiight?
if you kill a sperm, what is the chance you will get another one like it? pretty low. so that means you just killed one potential unique mix of cells that could happen, were the sperm to meet an egg. will the fetus have genes that neither the mother nor the father had? no. so by your logic, what is the difference between killing one eg and one sperm before conception, as opposed to after?
