In case of dominance, the phenotype will express itself and in case of incomplete dominance, both the alleles are unable to express themselves and would result in an intermediate phenotype. Hence, as the resulting progency showed pink flowers, it is due to incomplete dominance and the production of high amount of essential oils is due to the dominant allele.
