Consider sweet peas where aabb genotypic class produces purple flowers and all other genoitypic classes have white flowers. A)- If the parental generation is AA bb * aa BB what phenotypic ration do you expect in the F2 generation assuming complete penetrance ? B)- suppose now that only 75% of aabb individuals have purple flowers (that is, the penetrance of this trait is 75%. what phenotypic ratio do you now expect among the F2 plants? Also, in doing these types of crosses, what other phenomena (other than incomplete dominance) could explain the phenotypic ratio answered in part b.

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.
