Genetics – Phenotype vs Genotype

Transcript

A genotype refers to the genetic makeup of an individual. In other words, the DNA or genetic code is the individual’s genotype. The phenotype of an individual is the complete set of observable characteristics, including their behaviors that that individual possesses. The genotype does help to inform the phenotype, but the individual’s environment also heavily influences what the phenotype is. For example, a mutation in the LDLR gene is a part of the genotype, but having high cholesterol as a result and early blockage of the coronary arteries and other arteries, are the phenotype.
