In a species of the cat family, eye color can be gray, blue, green, or brown, and each trait is true breeding. In separate crosses involving homozygous parents, the following data were obtained: Cross P1 F1 F2 A green * gray all green 3/4 green: 1/4 gray B green * brown all green 3/4 green: 1/4 brown C gray * brown all green 9/16 green: 3/16 brown 3/16 gray: 1/16 blue (a) Analyze the data. How many genes are involved? Define gene symbols and indicate which genotypes yield each phenotype. (b) In a cross between a gray-eyed cat and one of unknown genotype and phenotype, the F1 generation was not observed. However, the F2 resulted in the same F2 ratio as in cross C. Determine the genotypes and phenotypes of the unknown P1 and F1 cats.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
