Genetics Unit Review

What is heritability?

• The influence of genes on an individual's traits

• The influence of the environment on an individual's traits

• The combination of genetic and environmental factors on an individual's traits

• The similarity between monozygotic and dizygotic twins

What is the purpose of twin studies?

• To determine the influence of genes on behavior

• To compare the physical characteristics of monozygotic and dizygotic twins

• To evaluate the impact of the environment on behavior

• To measure the concordance rates between twins

Which type of twins share 100% of their genetic information?

• Monozygotic twins

• Dizygotic twins

• Fraternal twins

• Identical twins

What is the Falconer model used for?

• To estimate the heritability of traits

• To compare the common and individual environments of twins

• To determine the cognitive influence on behavior

• To measure the concordance rates between twins

What did the Kendler et al. (2006) study aim to investigate?

• The heritability of major depression in twins

• The impact of the environment on major depression

• The difference between monozygotic and dizygotic twins

• The correlation between genetics and intelligence

What did the Kendler et al. (2006) study find about the heritability of major depression?

• It was higher in females than males

• It was higher in males than females

• It was equal in males and females

• It was not influenced by genetics

What did the Kendler et al. (2006) study find about the correlation of major depression in twins?

• Higher in monozygotic twins than dizygotic twins

• Higher in dizygotic twins than monozygotic twins

• Equal in monozygotic and dizygotic twins

• Not influenced by genetic factors

What is the operational definition of intelligence in adoption studies?

• IQ (intelligence quotient)

• Physical characteristics

• Educational level

• Curiosity

What did the Kendler et al. (2015) study aim to study?

• The influence of environment on cognitive ability

• The influence of genetics on pheromones

• The correlation between IQ and education level

• The difference between home-reared and adopted siblings

What is the purpose of adoption studies?

• To determine the differences between environmental and genetic factors

• To investigate the effects of selective placement

• To compare the cognitive abilities of adoptive children with the general population

• To analyze the correlation between adoptive parents and biological parents
