What is a mothers phenotype if her genotype is Ww?

A mother's phenotype with a genotype of Ww would depend on the dominance of the alleles represented by "W" and "w." If "W" is dominant over "w," the phenotype would display the trait associated with the "W" allele. If "w" is dominant or if both alleles contribute to a co-dominant or incomplete dominance expression, the phenotype may vary. In many cases, dominant traits are expressed in the phenotype when at least one dominant allele is present.
