Why are sperm cells different if they are all cells from the same parent?
In: Biology
Because we have a HUGE amount of genes in our body, only half of which (less actually in some sperm cells or eggs) are put into each cell.
Long ago, evolution decided that a wide genetic difference in a species creates a higher chance of survival.
So, by mixing up genes, it ensures that SOME offspring will be better adapted in a changing environment, and some offspring won’t,allowing only genes needed for survival in the current situation are passed, but also allowing genes that aren’t currently useful, but may become useful someday, to also hang around.
Its like investing In a bunch of different stocks to ensure you don’t lose everything because of one problem
