Explain Why Heredity May Contribute to Individual Differences in Intelligence

Your intelligence may be affected by heredity while your friends intelligence may be influenced by her genetic background. Explain why heredity may contribute to individual differences in intelligence but not necessarily contribute to group differences-Heredity.

Influence Of Heredity And Environment On Growth And Development Of A Child Education Summary

Intelligence genetics is special here because it offers the possibility of finding some of the connections between social and medical outcomes perhaps via genetic contributions.

. For example most families are concerned about improving the achievements of their children in schools. Heredity may range from genetic predispositions that are specific to each individual and that therefore potentially explain differences in individual characteristics eg temperament to those supposedly specific to certain groups and that therefore account for group differences in related characteristics eg gender and height and to. It may seem reasonable to expect that genetic influences on traits like IQ should become less important as one gains experiences with age.

Lots of factors can influence child development from ages 2 to 5. Intelligence is also strongly influenced by the environment. Through twins and adoption studies and the hereditary of schizophrenia It can be seen that hereditary has a bigger effect on personality as compared to family environment.

Today researchers generally agree that heredity and environment have an interactive influence on intelligence. To sum up. Differences in these characteristics are due to the change in the genes transmitted.

One of the most significant and chief causes of individual differences is heredity. There are genetic causes of some of the educational and social class differences in the populations studied and these overlap with the genetic causes of intelligence differences. Heredity nature is defined as the totality of biological acquired factors and is an important factor in the life of an individual.

Some of these influential factors are external like the environment the child is. Genetic variables on the other hand have a greater influence on personality traits. Social and cultural backgrounds play a very vital role in the development of intelligence.

Different characteristics of growth and development like intelligence aptitudes body structure colour of hair height weight and colour of eyes are highly influenced by heredity. 32 ASSESSING INDIVIDUAL DIFFERENCES Psychological assessment refers to the use of specific procedures for evaluating personal qualities behaviours and abilities of individuals. Heredity establishes the boundaries within which environmental variations determine the final outcome.

In spite of the recognition that genes contribute significantly to intelligence new research in epigenetics and neuroplasticity is revealing that our environment plays a strong role in how those genes are expressed. It depends on your social status and environment. Heredity strongly influence on Physical and Social Development.

Language socioeconomic status and stereotypes can all play a role in group differences. Fraternal twins also differ from each other because they are born out of different genes. In addition there are stable differences in individuals due to their experiences in life.

However genetic factors have a larger effect on personality traits. Heredity places an upper and lower limit on the IQ that can be attained by a given person. If it were very similar for all members of one species it would be very complicated to explain the appearance of new species with highly superior abilities.

Heredity sets the limitation which environmental differences decide the concluding result. These things contribute in shaping the intellect f a person. Individual families differ from one another with respect to culture and traditions.

Various studies have found the heritability of IQ to be between 07 and 08 in adults and 045 in childhood in the United States. Certain types of stimulations can switch on particular genes while not impacting others. Factors related to a childs home environment and parenting education and availability of learning resources and nutrition among others all contribute to intelligence.

Explain why heredity may contribute to individual differences in intelligence but not necessarily contribute to group differences. Many researchers believe that there is a reaction range to IQ which refers to the limits placed on IQ by heredity. Heredity plays a role in determining not only what physical traits an individual will possess but also how they.

50 of the variation of intelligence between people is 50 due to heredity NOT that your traits are 50 from heredity we can never say what percentage of an individuals intelligence is inherited but heritability focused on the extant of which differences amount people attributed to genes never an individual by why people differ. Chemicals can affect if the oxygen lack at birth that has negative impact in the mental. Explain the term individual differences.

The physical characteristics such as height weight colour of eye and skin social and intellectual behaviour are determined by heredity. These procedures describe people by specifying how they are different from or similar to other individuals. A certain degree of intelligence must be hereditary.

Individuals inherit various physical traits like face with its features colour of eyes and hair type of skin shape of skull and size of hands colour blindness baldness stub-finger and tendency to certain diseases like cancer and tuberculosis mental traits like intelligence abstract thinking. The visible difference between species of animals makes it palpable. There are a number of environment factors that affect intelligence of children which are chemicals food and disease level economic and social council education and peers.

Also drinking stimulants and alcohol. Genes inherited through biological parents It can contribute to intelligence. However that the opposite occurs is well documented.

Theory of natural selection. It is likely that a large number of genes are involved each of which makes only a small contribution to a persons intelligence.
