Zuzu the cat is homozygous for the allele that produces black fur pigment. She is also homozygous for the allele that prevents pigment from being placed into hair follicle cells, therefore, her fur is white. Which of the following terms best describes this observation?
Please just explain the correct answer. No need for everyone. Thank you!
