How do environmental factors lead to trait changes?

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.

was there more to the question like a picture or something? also i mean with no picture i think something that's not likely to be an educational impact would probably be the way the child is raised since it has special health care needs
