AP PSYCHOLOGY

Detailed explanation-1: -Most traits are shaped both by a person’s genes and by environmental factors. Environmental factors include everything outside of DNA that affects your traits. They are very broad and can influence you in many ways, either alone or in combination with genes.

Detailed explanation-2: -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-3: -Food, temperature, sunlight, and water are examples of environmental factors that can affect an organism’s traits. Many characteristics of plants and animals involve both inheritance and the environment. Learned experiences can change animal behavior and affect animal traits as they develop.

Detailed explanation-4: -Environmental factors affect expression of traits, and hence affect the probability of occurrences of traits in a population. The variation and distribution of traits observed depends on both genetic and environmental factors.
