18 Questions
What is heritability?
Heritability is the proportion of the variance in a trait that is due to genetic factors.
How does the heritability of intelligence change from childhood to adulthood?
The heritability of intelligence increases dramatically from childhood to adulthood.
Explain the concept of genotype-environment correlation in relation to intelligence.
Genotype-environment correlation refers to individuals selecting, modifying, and creating environments that are correlated with their genetic predispositions.
What is genetic amplification and how does it relate to intelligence?
Genetic amplification suggests that small genetic differences may become magnified as individuals develop.
What is Genome-wide Complex Trait Analysis (GCTA) and how does it estimate genetic influence?
GCTA is a method that estimates the net effect of genetic influence using DNA of unrelated individuals by predicting phenotypic similarity based on genetic similarity.
What did a recent twin study find about the genetic correlation of intelligence between ages 7 and 12?
The genetic correlation of intelligence between ages 7 and 12 was 0.75, despite increasing heritability from 0.36 to 0.49.
What is assortative mating greater for than any other trait?
Intelligence
How can GPS provide evidence of assortative mating for intelligence?
By correlating GPS between spouses
Is it known whether GPS assortative mating is greater for verbal or nonverbal ability?
It is an open question
What can be used to predict high intelligence?
GPS for intelligence from unselected samples
What does the text suggest might contribute to health outcomes and mortality?
GPS scores for intelligence
What can GPS scores be used to test regarding social mobility?
The extent to which genetic factors influence social mobility
What are some factors that are correlated with intelligence, education, and social class?
Intelligence, education, and social class are all correlated with each other.
What do twin and family studies suggest about educational attainment and social class?
Twin and family studies have shown that educational attainment and social class are somewhat heritable.
What have GCTA studies confirmed regarding intelligence, education, and social class?
GCTA studies have confirmed that there is a genetic basis for intelligence, education, and social class.
According to PSYC0036 Genes and Behaviour, what is one special finding related to the heritability of intelligence?
Heritability of intelligence increases dramatically from infancy through adulthood despite genetic stability.
What is the genetic correlation between intelligence and educational attainment?
The genetic correlation between intelligence and educational attainment is high.
What type of genetic variance is evidenced in intelligence according to PSYC0036 Genes and Behaviour?
There is evidence for non-additive genetic variance in intelligence.
Explore the correlations between intelligence, education, and social class in social epidemiology. Learn about the complex causes of these correlations, including shared genetic and environmental factors. Discover insights from twin and family studies on the heritability of educational attainment and social class.
