1. An organism that has a reduced or weakened form of a particular trait or function compared to the wild type, typically due to a genetic mutation that partially impairs gene function.
Usage: genetics; biology; technical

Examples

• The hypomorph showed decreased enzyme activity but retained some normal function.
• Researchers studied the hypomorph to understand how partial loss of gene function affects development.
• Unlike a null mutant, the hypomorph retained enough protein to survive.
• The hypomorph displayed intermediate phenotypes between wild type and complete loss-of-function mutants.
