7. How many genes does a human being have? Before the completion of the human genome project, many scientists were expecting to find 100,000 or more genes in our genome. This was based on the assumption that because we are one of the most complex creatures on Earth we should have lots of genes. However, it turned out we only have around 24,000 genes.
