What does incomplete dominance indicate in snapdragons?

Incomplete dominance in snapdragons refers to a specific pattern of inheritance in which neither allele is completely dominant over the other. As a result, when a plant inherits two different alleles for a particular trait, such as flower color, the traits from each allele blend together, producing a new phenotype that is distinct from both parent traits.

For example, if one allele codes for red flowers and another for white flowers, the offspring may exhibit pink flowers, which is a blend of the two parent colors. This phenomenon demonstrates how diverse traits can appear in the offspring, showcasing the unique genetic combinations that arise from incomplete dominance.

In contrast, complete dominance would show one allele overpowering the other, leading to the absence of blending, while the option regarding the percentage of dominant traits does not apply to the concept of incomplete dominance.
