Name: Class Date Polygenic Inheritance: Cat Coat Color Read aboutthe inheritance of cat coat color In each cat below, predict the phenotype of each genotype and color in each catl Make sure you indicate whether each cat is male or female One gene that affects coat color in cats is an x linked gene we'll call the pigment gene. One allele causes black fur (X) and one allele gives the cat orange fur (X"). These alleles act in a codominant manner, because when a cat has two different alleles (XB Xb), the cat has a pattern called tortoise shell, where the cat has both orange and black hairs. The Y chromosome does not have this coat color gene There is another gene that affects coat color in cats called the piebalding gene. This gene is on an autosomal chromosome and the alleles affect the amount of white patches that appear in the cat's coat, Some cats (ss) have o white patches and their other colors are blended, not patchy. Some cats (SS or Ss) have white patches and their other colors are…
