Detailed explanation-1: -Explanation: Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.
Detailed explanation-2: -The individual has no control over some of these factors, including developmental determinants, genetic makeup, gender, and age. Other factors that influence body weight over which the individual has potential control include level of physical activity, diet, and some environmental and social factors.
Detailed explanation-3: -Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene-either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.
Detailed explanation-4: -There are many different factors that contribute to obesity. An average figure from research studies estimates that obesity is about 40% genetic and 60% due to environmental factors, but there is a lot of variation in the scientific literature.
