What is Canalization and its examples?

Answer 1

Canalization is a developmental concept in Biology that refers to the ability of an organism to produce the same phenotype regardless of variability in its environment or genetic background. This phenomenon helps ensure that certain traits are reliably expressed even in the face of external disturbances. An example of canalization can be seen in the development of the eye, where genetic and environmental factors may vary, yet the eye typically develops into a functional organ in most individuals. Another example is the way certain behaviors, like nest building in birds, are consistently performed despite variations in individual experiences.
