Question

Quizplus · Accepted Answer

Genetic factors do influence body fat distribution. While genetic factors do contribute to obesity, the exact percentage of genetic contribution is debated and likely varies among individuals. Adoption studies have actually shown that the weight of an adopted child is more closely related to the weight of their biological parents, suggesting a stronger genetic influence than environmental factors. However, there is no single gene responsible for obesity, as it is a complex trait influenced by multiple genes and environmental factors.
