Genotype

The genotype is the genetic information of an organism. This information provides certain physical characteristics (phenotypes) that shape the species, but also develops the particularities that each individual may possess. The genotype comes in the form of DNA.

The genomes are contentivas units of thousands of genes, ie the genotype of a subject. Genes, on the other hand, are the minimum units that have instructions on which phenotypes should develop in the organism in question, according to the inheritance of its parents.

Difference between genotype and phenotype

To better understand the above, let’s compare these issues of genetics with the kitchen of a restaurant. The genotype would be the command (the paper) that indicates which dishes a table has requested. Everything that is written there, that is, the names of the dishes and possible instructions around the food, would be the genomes or genes, while the already cooked dishes would be the phenotype.

The genotype is then the set of instructions with which the physical traits of organisms must be “made”.

Importance 

The genotype is one of the most important structures of any organism , because, thanks to this information, both the physical body and some of the conditions that some individuals can present, such as congenital diseases, for example, are developed.

On the other hand, this code contains all the data collected throughout the existence on the evolution of a species. What changes have organisms undergone due to climatic conditions? Have they experienced mutations? Those answers and many others are embedded in DNA.

By studying the genotype of people, for example, the origins of diseases and their possible solutions can be determined. So the genotype and its study are very important to science.

Genotype examples

Next, you will see some of the data that may be contained in the genotype of a species.

  • Probabilities of suffering from some diseases because parents or grandparents have presented them, or due to alterations in the genetic code.
  • Physical traits that can be seen with the naked eye, such as skin, hair, and eye color. Also skin tone, facial features or hair density.
  • Body dimensions: height, predisposition to obesity, and more.
  • Nervous system problems.
  • Intolerance to certain substances.
  • Determine the 23 pairs of chromosomes.
  • Determine the sex that will manifest as a phenotype.
  • The types of blood.
  • Longevity.
  • Tendency to have allergies.
  • Having diabetes
  • Having asthma
  • Inherit heart problems
  • Predisposition to suffer some type of cancer.
  • Condition of metabolism.
