The answer is polygenic inheritance.
Many physical characters (traits) depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
For example, the color of the skin in humans. The color of the skin results from the interactions of several factors determined by different pairs of genes:-Certain genes could affect the metabolism of skin melanocytes.-Other genes can determine the distribution of melanin in the thickness of the skin.-Some genes could determine the relative amounts of each of the two possible types of melanin.-Others may affect the production of certain hormones involved in the activity of melanocytes.
One example that science would not be able to test
I often hear the comment, "Science has proved there is no God." Don't ever be bullied by such a statement. Science is completely incapable of proving such a thing.
I'm not saying that because I don't like science, but rather because I know a little about how science works. Science operates on induction. The inductive method entails searching out things in the world and drawing generalized conclusions about those things based on observation. Scientists can only draw conclusions on what they find, not on what they can't find.Science can prove that this is a god .A god that created the earth

Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
