7 billion combinations and counting.
That’s the current estimate for the number of unique human beings living on Earth right now. But this number barely scratches the surface of the number of unique humans that have ever lived on Earth, or how many humans will eventually live here.

This website will help explain meiotic cell division and how it leads to genetic variation while transmitting alleles from one generation to the next.
