22.Which of the following circumstances would indicate the greatest level of heritability of a trait?
a.Francois performs as well in school as the siblings with whom he was raised, even though he was adopted and is not genetically related to them.
b.D’artagnan prefers to watch movies on television, while his parents prefer to watch movies at a movie theater.
c.Luigi and his siblings are all about the same height.
d.Mario’s results on a personality test are far more similar to his biological parents than they are to his adopted parents.
23.Which of the following properties is widely accepted with regard to the relationship between genes and behaviors?
a.Genes actually change and break down as we age, which is why our actions change so dramatically as we get older.
b.Environmental influences typically make children within the family very similar to each other.
c.Genes cannot influence the kind of environment to which a person is exposed.
d.Heredity and environment interact dynamically throughout development.
24.The concept that genotypes are not the only things that control traits involves the fact that
a.dizygotic twins are virtually genetically identical while fraternal twins are not.
b.each genotype can produce a variety of phenotypes, depending on the environment in which a person lives.
c.recessive genes are more commonly expressed than dominant genes, especially in cases of polygenic inheritance.
d.the environment has little impact on behavior, as has been demonstrated in the results of the nature-nurture question.
25.The fact that a person with phenylketonuria can essentially mute the effects of their disease by controlling their dietary intake of a specific amino acid is an example of which of the following principles?
a.Heredity and the environment interact dynamically throughout development.
b.Genes can influence the environment to which a person is exposed.
c.Development is multidirectional in its nature.
d.Environmental influences typically make children within a family different.
26.Marvin has an exceptional amount of skill in athletics. Specifically, he is an extraordinary hockey player. Throughout his life he has chosen circumstances where he would be exposed to peers who also enjoyed hockey, and this has helped him develop opportunities to develop his talent. Marvin has been engaging in
a.genotyping.c.niche-picking.
b.phenotyping.d.heritizing.
27.________ refers to the process of deliberately seeking environments that fit one’s heredity.
a.Niche-pickingc.Base-rating
b.Context-selectiond.Polygenic inheritance
28.Jack and Jill are twins. Because he is a boy, Jack’s parents encourage him to run. However, they discourage Jill from engaging in athletic activity. As a result, Jack is much faster at running up a hill than Jill. The difference in Jack and Jill’s behavior is best explained by
a.nonshared environmental influences.c.polygenetic effects.
b.active gene-environment relations.d.niche-picking.
29.Although identical twins share 100% of their genetic code and are often similar, they are never truly “identical.” Which of the following explains these differences?
a.heterozygous chromosomal deviationsc.post-natal genetic mutations
b.active gene-environment relationshipsd.nonshared environmental influences
30.Larry and Ira are brothers who are two years apart in age. Larry went to one public school for his grade school years, but before Ira could go to that school the district underwent a rezoning. Ira, therefore, ended up going to a different school with less-qualified teachers and fewer resources. As a result, Larry tended to perform much better in school than Ira did. This example demonstrates the influence of
a.active gene-environment relationshipsc.nonshared environmental influences
b.niche-pickingd.asynchronous environmental genotypes
