Vildtype pea plants have inflated pea pods and round seeds. Constricted pea pods and wrinkled seeds are recessive phenotypes. You cross a pure breeding male plant with constricted pods and round seeds, to a pure breeding female plant with inflated pods and wrinkled seeds. All the F1 progeny displayed wildtype phenotypes. Use this information answer the following questions. You identify a new phenotype when crossing pea plants, sweet tasting peas, and bitter tasting peas. You generate pure breeding sweet and bitter lines and cross them together. The resulting progeny all have bitter taste. Based on these outcomes, what is the correct nomenclature for the gene controlling pea taste and the genotype of the F1s?

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.
