Answer

Brief Explanations:

To determine the inheritance pattern for Carly's wavy hair:

  • Codominance (A): Both traits are fully expressed (e.g., AB blood type), but wavy hair is a blend, not both straight and curly fully expressed. Eliminate A.
  • Dominant (B): A dominant allele would fully mask the recessive one, resulting in either straight or curly, not wavy. Eliminate B.
  • Incomplete Dominance (C): Occurs when the heterozygous phenotype is a blend of the two homozygous phenotypes. Carly’s father (straight, homozygous) and mother (curly, homozygous) likely have a heterozygous child (Carly) with wavy hair (a blend of straight and curly), matching incomplete dominance.
  • Polygenic (D): Traits controlled by multiple genes (e.g., height, skin color), but hair texture here is a single - gene - like blend, not polygenic. Eliminate D.
  • Recessive (E): A recessive trait is only expressed in homozygous recessive, and wavy is not a recessive - like blend of straight and curly. Eliminate E.

Answer:

C. incomplete dominance
