- B2,116, or 46 squared
- C8 million, or 2 to the 23

ANSWER: b
6What do we call a pairing of genes with one dominant and one recessive gene?
- Ahomozygous
- Bphenotypic
- Cheterozygous
- Dpolygenic
7What do we call the member of a gene pair that is more influential in terms of expressing a trait?
- Aphenotypic
- Bexpressive
- Crecessive
- Ddominant
8Assume that developing a sixth toe is a recessive trait that is controlled by a single pair of genes. If a child has six
toes, but both the child’s parents have normal feet, what can you conclude?- AThe child is heterozygous for the trait in question.
- BBoth parents are heterozygous for the trait in question.
- CBoth parents are homozygous for the trait in question.
- DThe child is adopted.
9What is the term for the specific pattern of genes that an individual inherits at conception?
- Aphenotype
- Bzygote
- Cpolygenic inheritance
- Dgenotype
10What is a person’s genotype?
- Atheir biological or chromosomal sex
- Bthe maternal contribution to their genetic makeup
- Ctheir genetic makeup
- Dtheir observable characteristics and traits
11Which of the following is determined at conception and is essentially fixed forever?
- Aphenotype
- Bsomatotype
- Cgenotype
- Dzygote
12Shane and Blane are monozygotic twins. However, people seldom get the two brothers mixed up because Blane
is almost two inches shorter than Shane. What can you conclude based on this evidence?- ABecause the brothers display different phenotypes, they must also have different underlying genotypes.
- BEven though both brothers share the same genotype, they display different phenotypes.
- CEven though both brothers display the same phenotype, they have different genotypes.
- DBlane is heterozygous for the “tallness” trait, and Shane is homozygous for the “tallness” trait.
13If a trait is described as polygenic, what does that mean?
- AIt is controlled by a single gene.
- BIt is controlled by a single chromosome.
- CIt is controlled by more than one pair of genes.
- DIt is controlled by genes on all 46 chromosomes.
14Skin colour is determined by three to five gene pairs. Based on this information, what type of trait is skin colour?
- Aa monogenic trait
- Ba polygenic trait
- Ca homozygous trait
- Da heterozygous trait
15Why are all human studies about the interaction of genes and environment correlational?
- Ato assess the effects of modern child-rearing methods
- Bto demonstrate the empirical nature of psychological research
- Cto meet ethical standards in research
- Dto disentangle the effects of genetics and experience on behavioural traits
16Which two individuals would we expect to have the GREATEST degree of phenotypic similarity?
- Amother and daughter
- Bmonozygotic twins
- Cdizygotic twins
- Dfather and son
17Four 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?- AEnvironmental factors have more influence than genetic factors in artistic interest.
- BBoth genetic and environmental factors contribute equally to artistic interest.
- CGenetic factors have more influence than environmental factors in artistic interest.
- DNeither genetic nor environmental factors contribute to artistic interest.
18Which of the following supports the hypothesis that intelligence is influenced by environmental factors?
- ATwins reared apart have similar intelligence scores.
- BMonozygotic twins are more similar than dizygotic twins on intelligence measures.
- CIdentical twins do not have identical intelligence scores.
- DThe correlations between dizygotic twins’ intelligence scores are around 0.60.
19Londra and Sondra are identical twins who have been raised together in the same home. Londra has developed
a psychological disorder, but Sondra does not appear to have the same disorder. What does this suggest about
the disorder if this pattern holds for other identical twins?- AGenetic factors have more influence than environmental factors in this disorder.
- BBoth genetic and environmental factors contribute equally to this disorder.
- CNeither genetic nor environmental factors contribute to this disorder.
- DEnvironmental factors have more influence than genetic factors in this disorder.
20Phong and Phan are identical twins who have been raised apart in separate adoptive homes. However, both
brothers have developed the same psychological disorder. What does this evidence suggest?- AGenetic factors have more influence than environmental factors in this disorder.
- BEnvironmental factors have more influence than genetic factors in this disorder.
- CNeither genetic nor environmental factors contribute to this disorder.
- DBoth genetic and environmental factors contribute equally to this disorder.
21Mary and Celine are identical twins who have been raised apart in separate adoptive homes. Mary has
developed a psychological disorder, but Celine does not appear to have the same disorder. What does this
evidence suggest?- AEnvironmental factors have more influence than genetic factors in this disorder.
- BBoth genetic and environmental factors contribute equally to this disorder.
- CGenetic factors do not influence this disorder.
- DGenetic factors have more influence than environmental factors in this disorder.
22What can we conclude about the heritability of intelligence, based on adoption studies?
- AGenotype determines intelligence.
- BAdoption studies do not provide enough evidence to assess the relative contributions of genes and
experience on intelligence. - CFamily environment is the strongest influence on intelligence.
- DBoth genes and environment contribute to intelligence.
23Which of the following comparison groups has a significant similarity with adopted children, based on research
on adopted children and intelligence?- Atheir biological parents
- Bboth sets of parents
- Ctheir adoptive parents
- Dneither set of parents
24Donavon was adopted at birth by Mr. and Mrs. Erndt. Although neither of his biological parents had much
musical ability, Donavon has become an excellent pianist, just like Mr. Erndt. What would this evidence suggest
if this pattern held up across multiple adoption studies?- AGenetic factors have more influence than environmental factors in musical talent.
- BEnvironmental factors have more influence than genetic factors in musical talent.
- CNeither genetic nor environmental factors contribute to musical talent.
- DBoth genetic and environmental factors contribute equally to musical talent.
25If you are working on the Human Genome Project, which of the following types of traits are you most likely to
be able to map?- Abehavioural traits, like aggression
- Bphysical traits that are highly polygenic
- Cdichotomous traits that are either present or absent
- Dpolygenic traits with high worldwide variance
26What do we know about the heritability of schizophrenia?
- ASchizophrenia is primarily social in origin, rather than biological.
- BSchizophrenia is inherited through the male line, which is why we don’t see heritability from mothers to
children. - CSchizophrenia is essentially a personality variant, which is highly heritable.
- DSchizophrenia likely results from an inherited vulnerability that interacts with experience.
27Dean is conducting a study in which he exposes rats to different amounts of noise to cause different amounts of
stress. He then evaluates whether the offspring of those rats have different reactions to stress. What sort of study
is Dean conducting?- Aepigenetic study
- Bbehaviour genetic study
- Cgenetic mapping study
- Dpolygenic study
