2. Priya has many different characteristics and traits. Some of these she sees reflected in her parents. She understands that the environment has also influenced how these traits have become expressed. She is a very outgoing individual with a variety of interests. During her biology class, she has come to understand that these are not the result of one gene but instead most likely due to ______.
polygenic inheritance
eugenics
fertilization
genome editing

evocative
recessive
active
passive

canalization
nurture
nature
6. Which term refers to the understanding that one gene may have an influence on a variety of outcomes?
gene editing
niche picking
pair bonding

trisomy on the 21st chromosome
a broken chromosome on one of the pairs
a missing chromosome on the 23rd pair
an extra chromosome on the 23rd pair
10. Which concept refers to the ability to study the whole genome at once in order to identify the relevant genes that are responsible for any certain trait?
pleiotropic effects
genome-wide association
gene dominance
concordance rate

True
False
12. What impact does the father’s sperm have on the 23rd pair of chromosomes in a zygote?
The father contributes either an X or a Y to determine the natal sex of the zygote
The father contributes an extra chromosome on the 23rd pair determining down syndrome
The father contributes the recessive gene for phenotypes relating to color blindness
The father contributes a Y for all zygotes on the 23rd pair of chromosomes
13. What impact on traits does deep canalization have?
Traits that have deep canalization tend to be the result of dominant gene structures
Traits that have deep canalization tend to show more multifactorial inheritance disorders
Traits that have deep canalization tend to be more resistant to gene therapy and genome editing
Traits that have deep canalization tend to have a self-righting tendency to produce the expected developmental outcome
14. Which is an example of a single gene disorder?
down syndrome
cystic fibrosis
fragile X
