The offspring inherits genetic characteristics from his parents. The environmental factors cc of the influence of parents, family, friends, schooling, society, culture, and all other experiences to which the child is exposed right from the moment of conception.
The nature-nurture controversy has philosophical roots. In the s, Locke, English philosopher, argued that the mind of a newborn is a blank: Locke believed that environment acts as the sole determinant of development.

Hereditary Factors Heredity refers to genetically transmitted characteristics from generation to the next. We inherit genetic code from parents. Because of genetic code, a fertilized human egg never grows into a dog or a mouse or any other animal.
The genotype expresses itself in observable appearance and behavior, which is called phenotype. The phenotype includes height, weight, eye color, and psychological characteristics such as intelligence, personality and creativity.
The genetic code provides the base on which phenotype grows and manifests. How can we know that human intelligence has a genetic basis? To do so, we have to infer the underlying genotypes from the observable phenotypic behavior. A strategy to understand genotypes from phenotypes is to examine the similarities between the intelligence level of children, and their parents and relatives.
Francis Galton was of the view that intelligence is largely inherited, and it runs in families. Correlations between IQs of brothers, sisters, children and their parents, and their distant relatives indicate that intelligence has a strong hereditary component Kagan and havemann, The correlation between the IQs of one child and another person selected at random would tend to be zero, while among the related individuals the correlations would be relatively high.
