Which of the following statements about the heritability of intelligence is LEAST consistent with the research evidence? ​
A)Intelligence is partly inherited.
B)Intelligence is correlated with brain volume.
C)Specific genes account for most intelligent behavior.
D)Heritability ratios can fluctuate over the life span.

Quizplus · Accepted Answer

Research indicates that intelligence is influenced by many genes, each contributing a small effect, rather than specific genes accounting for most intelligent behavior. Intelligence is indeed partly inherited, correlated with brain volume, and its heritability can fluctuate over time, making option C the least consistent with current evidence.
