But normally we have thousands of these different types of genes. Now, let's recall an important piece of information about diploid organisms. So in any diploid organism, in any to end organism we have, every single chromosome comes in a pair. So basically, in deployed organisms, chromosomes always come in pairs. And that's exactly why you have a second chromosome on the board. So in humans, even though we have 46 individual chromosomes, we actually have 23 pairs of chromosomes.
