Dominant vs. Recessive Phenotype



Dominant and recessive phenotypes relate to genetics. First, phenotypes are certain aspects produced by genotypes. So, if a gene calls for brown hair, the brown hair is the phenotype. Now, to be dominant the organism only needs one dominate pair of a gene. To be recessive the organism needs to have two pairs of the recessive gene. This picture of my stuffed animals exhibits dominant and recessive phenotypes. The bear has brown eyes while the wolf has blue eyes. Brown eyes are dominant while blue eyes are recessive. Other examples include the fact that a widow's peak is dominant while not having a widow's peak is recessive. Cleft chin is recessive while no cleft chin is dominant.
