What are TWO key criticisms of adoption and twin studies?
What does a heritability score tell us about HOW genes and environment interact in an individual to produce a trait?
A trait has a heritability of 0.15. This suggests:
Question 5 options:
The phenotypic variance is due entirely to genetic variation.
The phenotypic variance is due entirely to environmental factors.
The environment plays a much larger role in the phenotypic variance relative to genetics.
Both genetic and environmental factors play similar roles in the phenotypic variation.
Genetics plays a much larger role in the phenotypic variance relative to the environment.

To answer this question a personality psychologist recruits a huge sample of 2,593 identical twins and found that identical twins were similar in how snobby they were with an effect size of r=0.6. They also recruit a huge sample of 1845 fraternal twins and found that fraternal twins were also similar in how snobby they were with an effect size of r=0.4. Calculate the heritability coefficient for being a snob.arrow_forward

Why or why not?arrow_forwardPlease use the following table to compare qualitative (Mendelian) traits and quantitative traits (complex traits) - choose from the following.arrow_forward
- The heritability of intelligence as measured by IQ tests changes with socioeconomic status (SES).
