Hereditary factors were passed by our parents and ancestors to us. We humans differ from and resemble one another in many ways. Infants and children have individual ways of reacting to things. The study of genetics has grown out of a desire to understand how exactly the individual comes to be just that, an individual different from its peers. Are we the result of nature our genetic background or nurture our environment? Identify aspects of the life span perspective.
Heredity, or the genes that we are handed down from our parents cannot be controlled as of yet. Although identical twins are genetically identical and share the same family environment, identical twins raised together do not have identical personalities. We review the body of empirical evidence indicating that a genetic influences on cognition increase from infancy to adulthood, and b genetic influences on cognition are maximized in more advantaged socioeconomic contexts i. A typical adoption study may involve, for instance, comparing the concordance rates for the following two pairs: a child and her biological parent shared genes but not environments versus the same child and her adoptive parents shared environments but not genes. Some human traits such as having two eyes develop in any environment, but many important psychological traits are a product of the interaction of our genetic predispositions and our surrounding environment. The hereditary-environment controversy is reflected in empiricist-rationalist controversy.

In other words, heredity has potentiality and environment offers it a chance of bringing them out. Epigenetic changes are an especially good therapeutic target because they are reversible.
I am neither against environmentalists nor against geneticists altogether. Behavioral genetics seeks to find how not only heredity, but also environment, plays a role in the development of human beings. Hence, we can say that environment means all that is found around the individual. Further, this controversy has also been tackled by studying children of identical genetic constitution, or heredity including the children of identical multiple births and also on children whose genetic constitutions are known to be dissimilar. Conversely, all traits depend on the genotype on which they act, even traits that are very strongly affected by environmental differences.
The environmental influences are those which act upon the organism at the earlier stages of development, i. And he is quite strict when it comes to disciplining his children, so that explains their good manners. They have held one of the factors as constant and the other varied, on the principle that the differences so revealed can be attributed solely to the variant factor. On the other hand, the environmentalists are of the opinion that for the development of a plant only seed is not important but also environment like sunlight, manure, water, etc. Human behavior is made up of hormones which may be part of the genetic make up of heredity. However, we find more resemblances in identical twins because they are born out of monozygotic.
For example, children from disadvantaged backgrounds typically have less access to enriching books and other learning materials, less rigorous academic experiences, and lower quality interactions with both peers and adults.
