If the gene for curly hair is dominant and the gene for straight hair is recessive, from a dominant-recessive pairing, which of the following would be an individual's phenotype?

Question

Quizplus · Accepted Answer

If the gene for curly hair is dominant (represented by "C") and the gene for straight hair is recessive (represented by "c"), then an individual with even one "C" allele (i.e. CC or Cc) would have curly hair (the dominant phenotype), while an individual with two "c" alleles (i.e. cc) would have straight hair (the recessive phenotype). Therefore, the answer is B, as an individual's phenotype is their observable trait, and in this case, the phenotype would be curly hair if they have at least one dominant "C" allele. The other options (A, C, and D) do not accurately reflect an individual's phenotype in this scenario.
