23. Dominant vs. Recessive phenotype

A phenotype is the physical characteristic of an organism determined by genetic makeup, or which particular allele it has.. A dominant phenotype is one that makes up a majority of the population and a recessive phenotype is one that makes up a minority. Brown eyes are the dominant phenotype in the human population, while blue eyes are the recessive phenotype. This means that more people have brown eyes than any other colors, like blue or green.
