Thrifty phenotype

From Biology-Online Dictionary | Biology-Online Dictionary
Jump to: navigation, search



A resulting phenotype assumed to occur in poor nutritional condition in which a pregnant female can modify the development of her unborn child so that the child may be prepared for survival in an environment where resources are short or scarce.


Individuals with a thrifty phenotype will have a smaller body size, a lowered metabolic rate and a reduced level of behavioural activity. This idea has been based on Barker hypothesis.
