Suppose that a compound attractive to pollinators is produced by a plant in a pathway encoded by genes one (O) and two (T). You have obtained two pure lines of plants, one that produces the compound and one that does not (OOTT and oott, respectively). You cross them to obtain F1 plants that are heterozygous at both loci. (a) Use a branch diagram to visualize the possible outcomes of a cross between two F1 plants. (b) Calculate the expected proportion of offspring that will produce the attractant if this is a case of duplicate recessive epistasis. (c) What is the expected proportion of offspring that will produce attractant if this is a case of duplicate dominance?

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.
