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
In: Biology
Sperm & eggs are vastly different individually because of the random combination, swapping, etc. going on when cells divide genetic material to multiply.
Healthy normal humans have 23 pairs of chromosomes. The last one determines sex.
Men have XY, women have XX. Egg cells can only have X. Sperm cells can have X or Y.
(There are some people who have extras of either X or Y, or other chromosomes, but they are usually sterile & sometimes short-lived, often with health problems.)
