The paper presents the importance of the discoveries of behavioral genetics at the time and in the way of learning, growth, and development. Hereditary character transmission and the molecular mechanism of gene transmission are the main research topics of genetics in the 21st century, but modern genetics wants to further study the function and behavior of genes. Behavioral genetics studies the heritability of behavioral traits, a concept that summarizes how much of the variation of a trait is due to the variation of genetic factors. The research seeks to identify issues related to the expression of genetic material at the level of IQ, as well as the extent to which the environment and education have a role in defining behavioral traits, theories known in the scientific community since the last century. However, the latest research focuses on the results of new, DNA-based research rather than traditional studies of twins and families. From these results, it was concluded that this provides some support for the idea that the phenotypic structure of intelligence is due in part to genetic effects acting on a general factor of intelligence and also to more specific cognitive levels.
