The outward presentation, or features, of an individual’s genotype (genetic composition). The phenotype is the construction and operation that results from implementation of the genotype, much as a house is the outcome of a building contractor’s implementation of an architect’s blueprints. A phenotype consists of such obvious characteristics as eye color and hair patterns as well as less apparent traits such as blood type and proclivity for health or certain diseases.
The genotype for lipid metabolism, for example, may support effective use of lipids within the body (supporting health) or the tendency for high levels of lipids to accumulate in the blood (increasing the risk for cardiovascular disease (cvd)).
