HELP ASAP i will give brainliest Use the example of weight or obesity to explain how certain traits inherited by humans are a manifestation of both genetics and the environment?

Obesity occurs in families according to a clear inheritance pattern caused by changes in a single gene. The most commonly implicated gene is MC4R, which encodes the melanocortin 4 receptor. Genes give the body instructions for responding to changes in its environment. Studies of resemblances and differences among family members, twins, and adoptees offer indirect scientific evidence that a sizable portion of the variation in weight among adults is due to genetic factors.

I hope this helps
