Understanding Incomplete Dominance in Genetics

In a laboratory setting, a biologist is studying a new organism that exhibits a unique form of inheritance. The organism has two alleles for a gene that affects its color. One allele (A) is associated with blue color, while the other allele (a) leads to a green color. When an individual possesses one of each allele (genotype Aa), its phenotype is a blend of both colors, resulting in a teal appearance. This observation leads the biologist to conclude that this trait demonstrates a non-Mendelian pattern of inheritance.

Which of the following statements best describes the form of inheritance observed in this organism?
