Answer: The correct answer for the blank is- incomplete dominant alleles .
Incomplete dominance (also known as partial dominance) occurs when a dominant form of a gene does not completely masks the expression of another gene variant ( that is a recessive allele).
In this inheritance, a genotype with heterozygote condition ( with neither a dominant allele nor a recessive allele) results in an intermediate phenotype ( which depicts a blend of phenotypes that lies between the phenotypes of two homozygous parents).
For example- When a snapdragon red flower is crossed with a white flower, it produces pink snapdragon, representing incomplete dominance.
