Question

According to the findings of the Minnesota Study of Twins Reared Apart, which of the following traits have more than a 0.50 heritability ratio?

1) Intelligence
2) Height
3) Personality
4) Eye color

Answer 1

The Minnesota Study of Twins Reared Apart found that intelligence and certain aspects of personality have a heritability ratio greater than 0.50.

Step-by-step explanation:

According to the findings of the Minnesota Study of Twins Reared Apart, the traits that have more than a 0.50 heritability ratio are:

1. Intelligence: The study suggests that genetics play a role in determining intelligence, as identical twins raised together or apart showed a higher correlation between their IQ scores.
2. Personality: Certain aspects of our personalities, such as leadership, obedience to authority, and resistance to stress, have a genetic component and a heritability ratio greater than 0.50.

It's important to note that height and eye color are also influenced by genetics, but their heritability ratios may not be above 0.50.
