The trait for red hair is recessive, meaning that when a person expresses two copies of this allele they have red hair. What can be said about the phenotype and genotype of a red-haired individual versus a brown-haired (dominant) individual?
The phenotype of an individual with red hair does not directly correlate to the genotype, whereas the phenotype of a brown-haired individual provides direct information about his genotype.
For both brown-haired and red-haired individuals, the genotype can be determined simply by observing the phenotype of the individuals.
The phenotype of an individual with red-hair allows one to know his phenotype. An individual with brown hair also has a phenotype that gives enough information to deduce his genotype.
The phenotype alone can never imply anything about genotype for either individual.
The phenotype of an individual with red-hair allows one to know his phenotype, whereas deducing the genotype of a brown-haired individuals would require a closer look at generational breeding patterns.
