What term describes a phenotype that is a blend of two traits?

• A. Incomplete Dominance
• B. Codominance
• C. Autosomal
• D. Carrier

Answer: (A)

When neither allele is fully dominant, the heterozygous genotype produces an intermediate phenotype between the two homozygotes. This blending effect is characteristic of incomplete dominance. A classic example is snapdragon flower color, where crossing red and white results in pink offspring, rather than red or white. In codominance, both traits are expressed together (like spotted patterns or AB blood type), not blended. The other terms refer to either where the gene sits on the chromosomes (autosomal) or to someone who carries a recessive allele without showing the trait (carrier), which don’t describe a blended phenotype. So the blend of two traits in the offspring best fits incomplete dominance.
