Incomplete dominance.

Explanation:

Incomplete dominance refers to the pattern of inheritance when the heterozygote genotype expresses a blended phenotype. Here, the heterozygote exhibits a phenotype different from either of the homozygous individuals. It occurs when the dominant allele is not completely dominant over the recessive allele and the intermediate phenotype is expressed in the hybrid condition.

In the given experiment, crossing between the parent plants with yellow and red flowers given the progeny with the orange flower which is an intermediate phenotype of either of the parents. Therefore, it is an example of incomplete dominance.
