In a particular type of cat, coat color follows the dominant/recessive pattern of inheritance. The allele for a brown coat (B) is dominant to the allele for a white coat (b).

A cross between two white-coated cats would result in
A.
white-coated kittens only.
B.
white-coated kittens with brown spots.
C.
white-coated kittens or brown-coated kittens.
D.
brown-coated kittens only.

In a cross between two white-coated cats, both of which have the genotype bb (homozygous recessive for the white coat color), the offspring would also inherit the recessive b allele from both parents. This means that all of the kittens produced from this cross would also be b/b (white-coated).

Therefore, the answer is:

A. white-coated kittens only.
