In a species of the cat family, eye colour can be gray, blue, green or brown, and each colour is true breeding. In separate crosses involving homozygous parents, the following data were obtained: 5. Cross: P1 F1 F2 all green all green all green A % green : % gray green : % brown /16 green : /16 brown : 3/16 gray : /16 blue green x gray green x brown gray x brown C Explain this pattern of inheritance.

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.
