Verified step by step guidance

Step 1: Understand the concept of heterozygous genotype, which means having two different alleles for a particular gene (e.g., Aa).

Step 2: Review the types of inheritance patterns: Complete dominance, Codominance, Incomplete dominance, and Epistasis.

Step 3: Recall that in complete dominance, the dominant allele completely masks the recessive allele, so the heterozygous phenotype looks like the dominant homozygous phenotype.

Step 4: Recognize that in codominance, both alleles are fully expressed side by side in the heterozygous phenotype, without blending.

Step 5: Identify that in incomplete dominance, the heterozygous phenotype is a blend or intermediate of the two homozygous phenotypes, which matches the description of the problem.
