Quick Answer: What Have Some Studies Of Identical Twins Reared Apart Discovered About The Role Of Nature And Nurture?

What are some examples of nurture?

Nurture assumes that correlations between environmental factors and psychological outcomes are caused environmentally.

For example, how much parents read with their children and how well children learn to read appear to be related.

Other examples include environmental stress and its effect on depression..

How does nature and nurture affect intelligence?

Now, a study has shown that intelligence is a product of nurture as well as nature. Researchers found that children raised in wealthier and more educated households grow up to be smarter than those brought up in poorer homes.

What is the importance of adoption and twin studies?

Family, adoption, and twin studies can also be combined to provide more accurate estimates of genetic and environmental influences. For example, identical twins adopted into separate homes have been compared. Similarity between the separated twins provides strong evidence for the importance of genetic factors.

What do twin studies tell us about nature nurture?

Twin studies used to be almost the only way to compare the influence of genes against the environment on personality and behavior. Recent advances in genetics, however, suggest that opposing “nature” to “nurture” is misleading. Genes combine with the environment to produce complex human traits.

How have twin and adoption studies been used to address the nature v nurture issue?

The traditional way of studying nature versus nurture relies on twins. Because identical twins share the same genetic code, comparing the health of twins can help determine whether genetic or environmental factors play more of a role in their health.

How do twin studies help us understand the effects and interactions of nature and nurture?

When researchers seek to determine how personalities are developed, many look to twin studies to see how relative factors such as nature (genes) and nurture (environment) influence or dictate the way behavior and traits are established. The case centers on the dispute of what exactly drives us to be us.

Is personality more nature or nurture twin studies?

Overall, genetics has more influence than do parents on shaping our personality. Molecular genetics is the study of which genes are associated with which personality traits. The largely unknown environmental influences, known as the nonshared environmental effects, have the largest impact on personality.

Can identical twins be different genders?

Boy/girl monozygotic (identical) twins In very rare cases, identical twins can be different sexes. These twins begin as identical male twins. Like all males, they both have XY sex chromosomes, instead of XX like all females do.

Why do we study identical twins that were reared apart?

Many of those scientists had previously conducted twin studies. … As the researchers mention in their article, they studied monozygotic twins who were separated early in life and raised apart, because they provided a way to separate the influence of environmental and genetic factors on human characteristics.

What do twin studies reared together and apart Tell us about behavior?

A powerful method is studying identical twins reared apart from birth. Reared-apart identical twins resemble one another only because of their shared genes. Interestingly, research shows that identical twins reared apart and together are about equally similar in personality traits such as aggression and traditionalism.

Why are studies of identical twins raised in different environments extremely valuable?

Why are studies of identical twins raised in different environments extremely valuable in understanding the causes of a disease? They are extremely valuable in understanding the causes of a disease, because it differentiates between nature vs. nurture.

What DNA is different in identical twins?

It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother. (In contrast, fraternal twins are formed from two different sperm and two different eggs.)
