In my textbook, when reading about monohybrid inheritance from Gregor Mendel's experiment, it says that the allele for green pods is dominant over yellow , however when I was reading about dihybrid inheritance it uses G for yellow and g for green- when the genotype is RrGg it is said to be yellow. How can this be? Surely no matter what green should be dominant, can anyone explain? Does it just depend upon the species of pea plant, as my teacher told my class we are expected to know that green is dominant, so in an exam would i just assume green is always dominant?

In a dihybrid cross where traits are inherited independently you can get 4 different traits in offspring; round green, wrinkled green, round yellow, wrinkled yellow. The genotype RrGg is round and green pea (as round and green are dominant). You are usually told what the individual allele refers to and it's inheritance pattern.
