In the garden pea, orange pods (o) are recessive to green pods (+), and sensitivity to pea mosaic virus (v) is recessive to resistance to the virus (+). A plant with orange pods and sensitivity to the virus was crossed to a true-breeding plant with green pods and resistance to the virus. The F1 progeny were then test-crossed to plants with orange pods and sensitivity to the virus with the following results: 160 orange pods, virus sensitive 36 orange pods, virus resistant 165 green pods, virus resistant 39 green pods, virus sensitive 1.

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.
