Answer:

A. Ff Ee and ff ee

Step-by-step explanation:

The table shows approximately equal numbers of black-fur and white-fur offspring, as well as approximately equal numbers of black-eyed and red-eyed offspring. If one parent is Ff Ee and the other is ff ee, the second parent will only contribute recessive genes (f and e) to the offspring. The first parent will contribute F alleles to about half of its offspring, and f alleles to the rest, resulting in similar numbers of black fur (Ff) and white fur (ff) offspring. The same logic applies to eye color. Of the remaining answers, B is not possible because all of the offspring of these parents will have white fur. D is not possible because all of the offspring will inherit an F and an E from the first parent, so all will have black fur and black eyes. Choice C is a possible answer, but that parent combination should result in about 3/4 black-fur offspring, and 3/4 black-eye offspring.
