What are Model Organisms?

Model organisms are species which have limited complications in terms of breeding and sustaining under laboratory conditions. Model organisms are chosen based on their wide experimental characteristics.

Data is collected in abundance about the relative organisms and as such it is divided into three categories, genetic, experimental and genomic model organisms.

Genetic model organism is chosen based on their short life spans and their large reproducing numbers. Therefore genetic crosses can be set up on large scale over a number of generations which resulting in gene mapping and other phenomenon. An example is the mouse.

Experimental model organisms tend differ from the genetic model organism because of the extensive generation and insignificant genetic map details. However they tend to have other robust characteristics that can be of easy study and flexibility. An example is the African clawed frog.

Genomic model organisms are selected because of two reasons: their fundamental role in evolutionary equilibrium and/ or the superiority of their genome. An example is the puffer fish.
