DNA has a limited number of genes. Considering the enormous amount of functions they need to encode, the number of genes for each function becomes relatively small. 8 billion people and thousands of generations, we’re bound to have duplicates.
Yes, but the article says that certain combinations occur more often that if it was random. People with similar faces tend to have similar genes that are nor related to facial features.

I would say it’s even smaller in number. Because some combinations would not work and might kill you.
