Which of the following is said to reflect developmental instability (DI)?
A)physical fitness
B)visible symmetry
C)fluctuating asymmetry
D)Body Mass Index (BMI)

Question

Quizplus · Accepted Answer

Fluctuating asymmetry refers to small, random deviations from perfect bilateral symmetry in physical traits such as the length of fingers or the size of ears. This is thought to reflect developmental instability (DI), which is the inability of an organism to buffer against environmental stressors during development, leading to small variations in the development of bilaterally symmetric traits. A and D are not related to DI, while B (visible symmetry) is actually the opposite of fluctuating asymmetry.
