Detailed explanation-1: -Genetic factors are more important than environmental factors in determining an individual’s personal health risks.
Detailed explanation-2: -DNA Repair-Molecules damaged by environmental exposures like ultraviolet light or certain chemicals are incorporated into DNA, triggering cell death that may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer’s disease.
Detailed explanation-3: -Science tells us that the interactions between genes and environment shape human development. Despite the misconception that genes are “set in stone, ” research shows that early experiences can determine how genes are turned on and off-and even whether some are expressed at all.
Detailed explanation-4: -Environmental factors such as soil nutrients, temperature, water availability and light intensity influence the genetic and chemical diversity of plant populations. These environmental conditions can exert strong selection pressures, they could even determine the evolutionary course of plant populations [3, 4].
