In Order to Explain Principles of the Differences in Intelligence

question 244

Multiple Choice

In order to explain principles of the differences in intelligence between and within groups, the authors described a hypothetical tomato plant experiment. Based on this experiment it would be accurate to conclude that:

• A) if differences within groups are at least partly genetic in origin, then differences between groups are also genetic.
• B) the heritability differences between groups is 100% even though the within-group difference is due entirely to the environment.
• C) the variation within each group will result from genetic differences, but the between-group difference is explained by the different care received.
• D) heritability estimates are valid in regard to group differences, but not in regard to the variance found within a group.
