Price equation assumed that they do change, with "z" being the value of the character in the child population, then the full Price equation must be used. A change in character can come about in a number of ways. The following two examples illustrate two such possibilities, each of which introduces new insight into the Price equation. We focus on the idea of the fitness of the genotype. The index "i" indicates the genotype and the number of type "i" genotypes in the child population is: which gives fitness: Since the individual mutability "z" does not change, the average mutabilities will be:
