In some plants a red flower pigment, cyanidin, is synthesized from a colorless precursor. The addition of a hydroxyl group (OH-) to the cyanidin molecule causes it to become purple. In a cross between two randomly selected purple varieties, the following results were obtained: 94 purple 31 red 43 white How many genes are involved in the determination of these flower colors? Which genotypic combinations produce which phenotypes? Diagram the purple * purple cross.

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.
