9. Dominant vs. Recessive Phenotype

A phenotype is a physical appearance or an observable characteristic of an organism as the result of their genotype and their interaction with the environment. A dominant allele produces a dominant phenotype and the recessive allele produces a recessive phenotype. However, if a dominant allele is crossed with a recessive allele, the result will be a dominant phenotype because it surpasses the recessive allele. The brown eyes in the picture are the dominant phenotype and the blue eyes are the recessive phenotype. If brown eyes were crossed with blue eyes, it would result in brown eyes because it will dominate over the blue.
