One of the best ways to compute heritability is to compare:
A adopted children compare to adopted siblings
B blood relatives who live in different environments
C fraternal twins reared in different environments
D indentical twins reared in different environments,
I THINK IS A OR B ????
A. sure doesn't make any sense.
B. doesn't make much more sense.
Vedrana -- have you read your text book to actually LEARN about psychology?
I also suggest you look up unfamiliar words in a dictionary.
For sure the answer is not A, i got that wrong on my test
The correct answer is D - identical twins reared in different environments.
To understand why this is the best way to compute heritability, we need to understand what heritability means. Heritability refers to the extent to which differences in a trait within a population can be attributed to genetic factors. In other words, it measures the proportion of the variation in a trait that is due to genetic differences.
In order to determine heritability, we need to compare individuals who share different levels of genetic similarity and are exposed to varying environmental influences. By comparing identical twins, who share 100% of their genetic material, but were raised in different environments, we can assess the contribution of genetics to a particular trait. Any similarities between the twins can be attributed to genetics, as their shared genetic material is the only factor that remains constant. On the other hand, any differences between them can be attributed to environmental influences.
Comparing adopted children to adopted siblings (option A) would yield information about the influence of shared environment, but it does not account for the contribution of shared genetics. Blood relatives who live in different environments (option B) allows for the assessment of the genetic component, but it does not account for the environmental influences. Fraternal twins reared in different environments (option C) are similar to comparing adopted children to adopted siblings, where the focus is on the environmental contribution rather than the genetic contribution.
Therefore, the most accurate way to compute heritability is to compare identical twins reared in different environments (option D), as it simultaneously considers both genetic and environmental factors in explaining the variation in a trait.
