Context: This passage describes the agouti fur trait in cats:
Agouti is a fur pattern that is found in many mammals, including cats. When a cat has agouti fur, each of its hairs has bands of different colors. These bands give the cat's coat a striped or swirled pattern. When a cat does not have agouti fur, each of its hairs is a single color.
In a group of cats, some individuals have agouti fur and others do not. In this group, the gene for the agouti fur trait has two alleles. The allele for having agouti fur (A) is dominant over the allele for not having agouti fur (a).
This Punnett square shows a cross between two cats.
What is the probability that a cat produced by this cross will be heterozygous for the agouti fur gene?
A. 4/4
B. 1/4
C. 0/4
D. 2/4
E. 3/4
