Mutations in the 20,000 genes in the human genome can pave the way for disease. So far, more than 6,500 genetic mutations have been linked to specific diseases. Most of these mutations do not guarantee disease, and if they did, the gene would soon be removed from the genetic society by natural selection. Instead, they only slightly increase the likelihood of getting sick due to complex interactions with the environment and other genetic variants.
Before a disease can develop, it must banner design go through a complex process of steps, as in the case of cancer: a mutation alone is not enough to cause the disease. The evolution you can see and taste: skin color and the ability to digest dairy The genetic differences between people can be as many as a million letters, but the information these differences can provide to reconstruct human history is very limited. For positions in the genome with two different versions (such as someone with a C and someone with a T), 85% of them can be compared with one of our own chromosomes with a neighbor's chromosome, or with living on another planet.
This difference is drawn by comparing the chromosomes of one side of the person. We can even find it on two corresponding chromosomes in our own body, because half of our gene bodies are inherited from our father and half from our mother, and they are also different.
