From Biology-Online Dictionary
Jump to: navigation, search

Definition

noun

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.


Supplement

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.
