Comparing Human Genome And Doppelgängers

248 Words1 Page

Doppelgängers are two or more people who look alike. The human genome consists of over 3.2 billion base pairs. These base pairs can combine to make one gene, such as hair color or eye color. Genes are what we are made of, and they give us all different characteristics. But with around 7 billion people on the planet, there is bound to be more than one common gene between two people. This doesn’t include the deceased or unborn. For example, there are 7 billion people. About half are female and half are male, so the number decreases to 3.5 billion. If age is a factor, that number decreases to around 500 million. Authenticity brings that number to around 100 million. Say there are 100 nose shapes and 100 mouth shapes. That number is down 250,000.
