The argument that susceptibility to diabetes and obesity rose as people adapted to different climates provides an alternative to which idea?

A) antagonistic pleiotropy
B) hygiene hypothesis
C) Old Friends hypothesis
D) thrifty genotype hypothesis

Thrifty Genotype Hypothesis

The thrifty genotype hypothesis proposes that alleles that were advantageous in the past (for example, because they were “thrifty” and stored nutrients well) may have become detrimental in the modern world, contributing to metabolic syndrome, obesity, and type 2 diabetes.

Antagonistic Pleiotropy

A hypothesis suggesting that a single gene can affect multiple traits in a way that is beneficial in some aspects but detrimental in others.

Hygiene Hypothesis

Suggests that a lack of early childhood exposure to infectious agents, symbiotic microorganisms, and parasites increases susceptibility to allergic diseases by suppressing the natural development of the immune system.
