Experts estimate that the heritability of intelligence is approximately 50%. This suggests that
A) 50% of a person's intelligence is due to genetic inheritance.
B) 50% of a person's intelligence is due to environmental factors.
C) 50% of the variability in intelligence in a population of individuals is due to variations in genetic inheritance.
D) 50% of the difference in average intelligence between different ethnic groups is due to genetic inheritance.
Heritability
A measure of how much of the variation in a trait within a population can be attributed to genetic differences among individuals.
Intelligence
The ability to learn from experience, solve problems, and use knowledge to adapt to new situations.
Genetic Inheritance
The process by which genetic information is passed from parents to offspring through their genes.

Final Answer :
C
Explanation :
The heritability of intelligence estimates that 50% of the variability in intelligence in a population of individuals is due to variations in genetic inheritance. This means that in a population of individuals, 50% of the differences in intelligence levels are due to differences in their genes. It does not suggest that 50% of a person's intelligence is solely due to genetic inheritance or that genetics are the only factor influencing intelligence. Environmental factors also play a significant role in intelligence, with some experts estimating that environmental factors may account for up to 70% of intelligence differences. Finally, the heritability of intelligence does not account for differences in intelligence between different ethnic groups, as intelligence is a complex trait influenced by many factors beyond genetics.
