IS A CORRECT ANSWER OR D

"highly correlated" is a very ill defined term. Heritability accounts for slightly less than fifty percent of the score on IQ tests. Is that highly coorelated? (Note in my usage of highly). In twins, the "maternal factor" (heritability) accounts for about 20 percent of the covariance between twin studies, and about five percent between siblings.

The controversy between heritability and environment is lasting, no definitive studies are existing. It is very difficult to get a meaningful statistical discrimination, and in many instances, the constructs of the IQ measuring instrument overshadow the sample.

I think the best answer is A, although C if worded differently would have some appeal. There appears to be a large random measurement factor in IQ tests.
I want to warn you: There are many folks lined up on differing sides of the IQ controversy, and many professionals would not agree with me on what I espoused on the difficulty of correlating IQ scores with intelligence, and the inadequate sampling evidence existent. Your grader may have a bias that IQ is a more exact science that I have proposed.

D was wrong on my test.

The correct answer is A. "Within groups, differences in intelligence are highly correlated with heritability; between groups, differences are highly correlated with the environment."

To understand why, let's break down the answer choices:

A. Heritability; environment: This answer correctly states that within groups, differences in intelligence are highly correlated with heritability, which refers to the proportion of differences in intelligence that can be attributed to genetic factors. Additionally, between groups, differences in intelligence are highly correlated with the environment, meaning that variations between different groups (such as different populations or cultures) are primarily influenced by environmental factors.

B. Environment; genes: This answer is incorrect because it reverses the order of relationships. While environmental factors can play a role in within-group differences, they are more strongly associated with differences between groups. Genetic factors, on the other hand, are primarily responsible for within-group differences in intelligence.

C. Heritability; random error in measurement: This answer is incorrect because heritability refers to the proportion of differences in a trait (such as intelligence) that can be attributed to genetic factors, not random error in measurement.

D. Genes; the heritability estimate: This answer is incorrect because it inaccurately equates genes with the heritability estimate. While genes do play a role in determining intelligence, the heritability estimate is a statistical measure that quantifies the degree to which differences in a trait (such as intelligence) are due to genetic factors.

In summary, answer choice A correctly describes the relationship between within-group differences in intelligence (heritability) and between-group differences (environment). Therefore, option A is the correct answer.
