There should be more individuals with the dominant trait so the population is not in equilibrium.
One way is by comparative anatomy. Comparing the similar bone structure of animals gives more proof of this theory. Also, the location of some animals compared to other animals of similar species is very convenient, and supports the theory of natural selection.

<span>Proto-oncogenes are genes that normally help cells grow. When a proto-oncogenemutates (changes) or there are too many copies of it, it becomes a "bad" gene thatcan become permanently turned on or activated when it is not supposed to be. When this happens, the cell grows out of control, which can lead to cancer.....Is this what you need ?</span>
