%
Explanation:
As per the Hardy Weinberg's equation -
represents the frequency of population with phenotype expressed by homozygous recessive genotype
represents the frequency of population with phenotype expressed by homozygous dominant genotype
and
represents the frequency of population with phenotype expressed by homozygous recessive genotype
Given -

As per first principle of Hardy Weinberg's equilibrium

Substituting the value of q in above equation, we get -

As per second principle of Hardy Weinberg's equilibrium

Substituting the given values in above equation, we get -

Frequency of heterozygous animals with agouti fur is
%
It is a genetic change that causes differing characteristics between organisms in a certain species.
