* We need to know the specific trait: Dominant alleles control specific traits, like eye color, hair color, or a particular disease. Without knowing the trait in question, we can't predict her appearance.
* Dominant alleles don't always mean a specific appearance: Some dominant alleles produce a specific phenotype (like Huntington's disease), while others simply contribute to a trait in a way that might be hard to pinpoint (like height).
Example:
* Trait: Eye color
* Dominant allele: Brown eyes (B)
* Recessive allele: Blue eyes (b)
* Woman's genotype: BB (two dominant alleles)
* Phenotype: Brown eyes
To figure out her phenotype, we need to know the trait and the specific dominant alleles involved.
