Multiple Choice

Use the following to answer questions :
Scenario II
For centuries,people have made the observation that intelligence seems to run in families.In modern times,psychologists have confirmed that,indeed,there is a strong genetic component to intelligence.The degree of the association between genes and intelligence can be quantified using the heritability coefficient (h²) .In a population of diverse individuals differing in age,gender,race,and socioeconomic factors,the heritability of intelligence is approximately .5 to .7.This means that about 50-70% of the variability in intelligence scores is associated with genetic factors.Interestingly,the heritability coefficient changes depending on the group under investigation.For example,among wealthy children,the heritability coefficient exceeds .7 because the environments of these children are highly homogeneous.Among poor children,it drops to about .1.The heritability coefficient also tends to increase with the age of the population under investigation.For example,the heritability coefficient is approximately .3 in 3-year-olds and approximately .9 in 65-year-olds.
-(Scenario II) In which of these science-fiction scenarios would the heritability of intelligence be the lowest?

• A)a space colony populated by the offspring of only 20 original colonists
• B)a population of genetic clones
• C)a utopia where each child receives the same high-quality educational experiences
• D)a brutal dictatorship that keeps its entire population in poverty
