A red flower is crossed with a white flower, and the result is a pink flower. What is this an example of?

Codominance refers to a genetic scenario where both alleles in a heterozygote are fully expressed, leading to a phenotype that exhibits traits from both parents distinctly. An example would be a flower that displays both red and white patches, rather than blending into a pink color. Therefore, codominance does not apply since the result is not a mix but rather a clear expression of both traits.

Complete dominance occurs when one allele completely masks the effect of another in a heterozygote. In this case, if red were completely dominant over white, all offspring would exhibit the red phenotype, not a pink one. Thus, complete dominance does not explain the pink flower's emergence.

Bi-dominance is not a standard term in genetics and is not recognized as a mode of inheritance. It may imply a situation where two alleles exert influence, but it lacks the scientific backing and specificity of recognized terms like incomplete dominance or codominance. Therefore, it is not applicable to this scenario.
