The two most basic influences on social behavior are genes (the chemical instructions that people inherit from their parents’ DNA) and the environment (all other, noninherited factors). … This is because people’s environments are just as important in influencing behavior as their inherited genes.
How does heredity influence behavior?
Genes, via their influences on morphology and physiology, create a framework within which the environment acts to shape the behavior of an individual animal. The environment can affect morphological and physiological development; in turn behavior develops as a result of that animal’s shape and internal workings.
How would heredity be influential?
Heredity influences several factors that contribute to fitness, such as body size and muscle fiber composition. Whether we are tall or short is determined by heredity. The percentage of slow-twitch and fast-twitch muscle fibers found in skeletal muscle is determined genetically.
Why is heredity so important?
Genetic variation is important because it helps populations change over time. In any species, some individuals in a population will have variations that are more likely to help them survive. Variations that help an organism survive are passed on to their offspring.
