At the molecular level, the heat comes from the agitation of the molecules and therefore their atoms. This increase in agitation causes the molecules to be less condensed between them and will separate after breaks in the intermlecular bonds. This distends the material, as we see when we heat a metal, or a transformation of the phase of the material, such as melting ice or boiling water.
Why human skin coloration is not sufficiently explained by polygenic inheritance? it is because of the other aspect that affects the skin, for example sun exposure which is the effect of environment not by genes. If a person is exposed in the sun, her skin gets darker compare to what it used to be.
Dogs, cats and humans each contain approximately 2.5–3 billion base pairs in their DNA, comprising about 20,000–25,000 individual genes.
So we have the same DNA components
Hope this helps! Please correct me if I'm wrong :)
I know the method that will help you to do it by yourself. Try to search a soft that builds diagrams online. By the first link you will get the soft you need. Or use excel to build it. Just enter meanings to a columns and then use Excel's tools to build any kind of diagrams.
