Question

The thrifty genotype hypothesis proposes:

(A) that alleles causing diseases such as diabetes were advantageous at some point in our evolutionary history
(B) that modern diets are often rich in nutrients that were more scarce over our evolutionary history
(C) that conditions experienced by a developing fetus can affect physiology throughout life
(D) a and b are correct

Answer 1

The thrifty gene hypothesis proposes that alleles causing diseases such as diabetes were advantageous at some point in our evolutionary history and that modern diets are often rich in nutrients that were more scarce over our evolutionary history.

Step-by-step explanation:

The thrifty gene hypothesis proposes that alleles causing diseases such as diabetes were advantageous at some point in our evolutionary history and that modern diets are often rich in nutrients that were more scarce over our evolutionary history. Therefore, the hypothesis suggests that these alleles were favored by natural selection because they allowed individuals to store more body fat and survive famines. Therefore, option (A) and option (B) are correct.
