is every sperm cell nearly identical and just connects and mixes differently with the egg or does it work like that meme image where every sperm cell is capable of creating vastly different human beings? i know it sounds dumb, im just having late evening thoughts and wanted to leave one here. thanks upfront 🙂
edit: after reading the replies i realise i should have just left that question in my head. i understand the general biology of it all, just didnt stop to think about it before posting. as i said, slow brain evening thoughs…yea, it makes sense, thanks people. lol

You should read up more on human reproduction.
The short of it, is that sperm cells are not identical. They are similar in genetic composition, but every time a gamete is formed, it gets half of a shuffled version of the DNA of the person.
Technically you’re passing your genes, but not all of them.
Imagine you have two genes that code for a trait differently, lets call them A and B. Say, that every time there is A in the genome, B is not expressed, or is expressed less. After recombination, A could be passed 50% of the time, as well as B, or a combination of them. In this case, a child could be getting either trait, or both from a parent.
That’s where the difference comes from.
