1. What does the term ‘genome’ refer to?
a. The complete set of genes an organism produces
b. A unit of heredity which is transferred from a parent to offspring and is held to
determine some characteristic of the offspring
c. A self-replicating material that is present in nearly all living organisms as the
main constituent of chromosomes. It is the carrier of genetic information
d. 98% of the DNA in the humans that is functionless and serves no purpose
2. Match the following terms with their definitions.
a. Percentage of variance
b. Heritability
c. Environmentality
i. The percentage of observed variance in a group that can be attributed
to non genetic differences.
ii. The fact that individuals vary, or are different from each other, and this
variability can be partitioned into percentages that are due to different
causes.
iii. A statistic that refers to the proportion of observed variance in a group
of individuals that can be accounted for by genetic variance.
3. Lisa got a haircut last week and decided that she wants to pierce her ears soon. Her
monozygotic twin sister dyed her hair red and has a few tattoos. What is true about
these twin sisters?
a. They differ in karyotype
b. They differ in phenotype
c. They differ in genotype
d. They differ in banotype
4. What is true about heritability?
a. It can be applied to a single individual
b. it is consistent between different countries at the same point in time
c. It is a precise statistic, computed using correlations
d. It provides useful information in identifying the determinants of personality
5. What is true about the nature-nurture debate?
a. At the individual level, there is no nature-nurture debate.
b. At the level of the population, there is no nature-nurture debate.
c. Genetic factors are bigger than environmental factors
d. Environmental factors are bigger than genetic factors
