The essential characteristics that are inherited by human beings are reflexes, physical structure, intelligence, innate drives, and temperament. The biologists say that the differences in the qualities or traits of people or groups are because of the differences in heredity. These are duly supported by sociologists and psychologists in their assertion.
Effects of Heredity
The supporters of the heredity theory are the authors such as Karl Pearson, Galton, Mc Dougall, and others. Some of the arguments that brought forward the Heredity and the Environment study, the prominent ones are stated in our Heredity and Environment assignment help desk.
He has revealed that the probability of the happening of gifted children is higher if the fathers have superior intelligence.
Karl Pearson has concluded that the influence of an environment is less than of heredity to determine the importance of differences in humans. It is possible for measuring the relative efficiency of two. He provided evidence that two people within community heredity is 7X more important compared to the environment.
Similar to Pearson, many researchers have revealed that groups with higher intellectual or social rating have given more persons of distinction. For example, royal families produce more geniuses compared to other families.
The Difference in Intelligence Levels of the Various Occupation Groups
Some writers have revealed considerable differences between the various intelligence levels of various occupational groups. For example, it has been revealed that the children of their professional parents have an intelligence quotient of 116, managerial class and semi-professional classes have 112, skilled trades, clerical, and retail business have 107.5, slight skilled have 98, and children of rural and urban labourers and farmers have 96.
However, these are not because of heredity. These are vital facts, however, conclusions drawn are superficial. They give evidence about a common observation. Children born in those families that possess distinction are considered more to develop intellectual traits.
