Definitions:

Gene Duplication

Paralogs

Genes that arise by duplication within the same organism, often developing new functions while retaining some characteristics of the original gene.

Functional Redundancy

The phenomenon where multiple species or genes perform similar functions within an ecosystem or biological system, providing resilience against environmental changes or perturbations.

Engrailed Gene

A gene that plays a crucial role in defining the segments and patterning of the body parts in many organisms, including their limb development.
