Question

Carly has wavy hair. Her father has straight hair, and her mother has curly hair. Which type of inheritance pattern is responsible for Carly's wavy hair?

Answer 1

Carly's mother has a dominant trait of curly hair, so therefore, the dominant trait(curly hair) is stronger than the recessive trait(straight hair).

Answer 2

Answer:

Incomplete dominance.

Explanation:

Incomplete dominance occurs when the heterozygous genotype has an intermediate phenotype in relation to the phenotypes of two parental homozygotes.

As every gene is transcribed in RNA (and this will be used as a template in translation for a protein to be produced), in the case of incomplete dominance, during translation, one allele generally produces a functional protein, while the other produces a non-functional protein . As a consequence, the intermediate phenotype is generated as a mixture of one and the other.
