In Persian cats, there is a hereditary condition called polycystic kidney disease (PKD), which can lead to kidney failure and death. This is a dominant disorder. At one point, as many as 50% of Persian cats had PKD. Recently, however, the prevalence of PKD has dropped dramatically as DNA testing that can detect affected cats has been developed. As a result, breeders have become aware of this genetic disorder and have been careful not to breed affected cats. tan colored, fluffy Persian cat © Takashi(aes256) 2012 Creative Commons, CC BY-SA 2.0 Part 1: A cat that is heterozygous for PKD is bred with a cat that does not have PKD. Use a Punnett square to help determine the probability of the possible genotypes and phenotypes in the offspring. Explain your results in paragraph form. Part 2: If a cat does not have PKD, what can you conclude about the genotypes and phenotypes of its parents? Explain your answer in paragraph form.
