Is There Really A Difference Between Genotype and Phenotype?

Genotype is the genetic makeup of an individual with reference to a trait or multiple traits. They are the collection of genes passed from parents to the children. They are divided into six- AA, AC, AS, CC, SC and SS.

A lot of people are familiar with just 4 types of the genotypes, which includes; AA, AS, SS and SC. The truth is that ac genotype is rare and unpopular, unlike the other three. SS and AC genotypes are the abnormal genotypes, which are also called the sickle cells.

What is Phenotype?

The phenotype is the physical and behavioral traits of an organism, for example, size and shape, metabolic activities, and patterns of movement are the symbolic traits of phenotypes.  Even though you have the same parents and you come from the same family, it doesn’t mean you will grow and look the same way with your siblings.

The fitness of an individual is evaluated on its phenotype and not on he’s genotype. For instance, there is not a single gene coding for blue eyes. Blue eyes is a phenotype.

More examples of Phenotype includes:

  • Hair color
  • Height
  • Sound of your voice
  • Certain behaviors
  • Size of a bird’s beak
  • Length of a fox’s tail
  • Color of the stripes on a cat
  • Size and shape of the spots on a dog’s back
  • An individual’s shoe size

In conclusion,your genotype plays a critical role in your development and phenotypes are the actual visible characteristics including that one can see.
