Which of the following produces an intermediate phenotype?
A) codominance
B) sex-linked inheritance
C) polygenic inheritance
D) simple Mendelian inheritance
E) incomplete dominance
Intermediate Phenotype
A phenotype that exhibits a blend or mixture of characteristics between two extremes, often seen in incomplete dominance genetic scenarios.
Incomplete Dominance
A genetic phenomenon where neither allele of a gene fully dominates the other, resulting in a phenotype that is a blend or intermediate between the two parent alleles.
Codominance
A genetic scenario where two alleles of a gene are expressed equally in the phenotype of the organism.

Final Answer :
E
Explanation :
Incomplete dominance is when the heterozygous phenotype is an intermediate of the homozygous dominant and homozygous recessive phenotypes. The classic example is the flower color inheritance in snapdragons - red and white flowers can produce pink offspring when crossed.
