The Genetic Lottery of Meiosis

You are literally a walking genetic lottery winner. It is all thanks to a process called

meiosis. While mitosis is just your cells making boring clones of themselves,

meiosis is where things get wild. Your body takes chromosomes from your mom and dad

and actually forces them to swap DNA during crossing over. Then it shuffles

them randomly to create four completely unique cells. This genetic remixing means the odds of

you existing exactly as you are right now are basically zero. That biological

chaos is actually crucial because it fuels natural selection and keeps our species surviving.
