Stefanie is a young farmer growing new and heritage pumpkins. In her rows of pumpkins she finds a dark orange pumpkin with warts and a green pumpkin with smooth skin. She knows that orange skin color is dominant in pumpkins, but she cannot find any information on the inheritance of warty skin in pumpkins. She decides to cross the pumpkins to determine if warty skin is a dominant or recessive trait. If you hypothesize that warty skin is the dominant trait... -Then, based on your hypothesis, predict the results of the F1 and F2 dihybrid crosses between the orange warty pumpkin snd the green smooth pumpkin. (Assume these pumpkins are homozygous for both traits.

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.
