Question

Quizplus · Accepted Answer

Studies have shown that adopted children tend to have body weights that are more similar to their biological parents than their adoptive parents, indicating a strong genetic influence on weight gain. Obese people cannot change their genomes or epigenomes, but their lifestyle choices can influence gene expression. While exercise may not have a direct impact on genetic influence, it can still help with weight management and overall health. Identical twins are more likely to have similar body weights than fraternal twins, indicating a genetic component, but they are not half as likely.
