How can an organism measure fitness?
The central concept of natural selection is the evolutionary fitness of an organism. Fitness is measured by an organism’s ability to survive and reproduce, which determines the size of its genetic contribution to the next generation.

Why is relative fitness important?
which is only important because it shows that we can in fact talk about the rate at which selection works. The relative fitness highlights a couple of important points, however. Most importantly the relative fitnesses have the term (1-sq), that is there is a gene frequency in them.
