Frage 17 von 27

1

Four sisters were all raised in the same household by parents who are very creative and artistic. Anna and Betty
are the biological children of their parents, while Cassie and Deanna were adopted as infants into the family. Like
their parents, Anna and Betty are artistically inclined and enjoy working on creative projects. Cassie and Deanna
are not particularly interested in artistic endeavours even though they’ve received a lot of exposure to art and a
lot of encouragement for creative work. Which of the following conclusions would be reasonable if this pattern
occurred in a variety of similar families?

Wähle eine der folgenden:

  • Environmental factors have more influence than genetic factors in artistic interest.

  • Both genetic and environmental factors contribute equally to artistic interest.

  • Genetic factors have more influence than environmental factors in artistic interest.

  • Neither genetic nor environmental factors contribute to artistic interest.

Erklärung

  • Twins reared apart have similar intelligence scores.

  • Monozygotic twins are more similar than dizygotic twins on intelligence measures.

  • Identical twins do not have identical intelligence scores.

Frage 24 von 27

1

  • Environmental factors have more influence than genetic factors in musical talent.

  • Neither genetic nor environmental factors contribute to musical talent.

1

If you are working on the Human Genome Project, which of the following types of traits are you most likely to
be able to map?

Frage 26 von 27

1

What do we know about the heritability of schizophrenia?

Wähle eine der folgenden:

  • Schizophrenia is primarily social in origin, rather than biological.
