Resource summary

Question 1

Question
How many pairs of genes do we have?
Answer
  • 23
  • 46
  • 12
  • 16

Question 2

Question
Define Mitosis
Answer
  • Sexual reproduction - chromosome pairs of 2 parents integrating and mixing genetic information, and producing 4 cells, each with 1/4 of the number of chromosomes from the original cells.
  • Regular reproduction and replication of body tissue - a single cell divides, producing 2 cells.
  • Sexual reproduction - chromosome pairs of 2 parents integrating and mixing genetic information, and producing 4 cells, each with 1/2 of the number of chromosomes from the original cells.
  • An error in cell reproduction, resulting in mutations

Question 3

Question
Define Meiosis
Answer
  • Sexual reproduction - chromosome pairs of 2 parents integrating and mixing genetic information, and producing 4 cells, each with 1/2 of the number of chromosomes from the original cells.
  • Sexual reproduction - chromosome pairs of 2 parents integrating and mixing genetic information, and producing 2 cells, each with 1/2 of the number of chromosomes from the original cells.
  • Sexual reproduction - chromosomes pairs of 2 parents integrating and mixing genetic information, and producing 4 cells, each with 1/4 of the number of chromosomes from the original cells.
  • Sexual reproduction - chromosomes pairs of 2 parents integrating and mixing genetic information, and producing 6 cells, each with 1/3rd of the number of chromosomes from the original cells.

Question 4

Question
What are the 4 types of mutations?
Answer
  • Inversion, containments, transbiosis, synductions
  • Containments, Deletions, duplications, transbiosis
  • Inversions, deletions, duplications, translocations
  • Translocations, duplications, inversions, synductions

Question 5

Question
Which of the following is an example of a dominant-recessive gene relationship? Tick all that apply
Answer
  • Mathematical ability / creative ability
  • Red hair / blonde hair
  • Brown eyes/ blue eyes
  • Tall height / short height

Question 6

Question
Cystic Fibrosis is an example of a disorder in which gene?
Answer
  • Dominant gene
  • Recessive gene
  • Co-dominance
  • None of the above

Question 7

Question
What are the chances of inheriting a genetic disorder stemming from a dominant gene?
Answer
  • 1 in 6
  • 1 in 4
  • 1 in 20
  • 1 in 2

Question 8

Question
What is the chromosomal abnormality that occurs in Down Syndrome?
Answer
  • Only 18 chromosome pairs instead of 26
  • XO expression instead of XX
  • 3 chromosomes instead of 2
  • 1 chromosome instead of 2

Question 9

Question
What does the process of Amniocentesis do?
Answer
  • Prenatally diagnoses genetic disorders of the foetus through taking tissue sample, or needling the chromosome.
  • Prenatally diagnoses genetic disorders through ultrasound
  • Prenatally examines risk of down syndrome through testing the fluid at the back of the neck
  • Prenatally diagnoses genetic disorders through pre-implantation (IVF treatment).

Question 10

Question
What is the % of shared genes of monozygotic and dizygotic twins?
Answer
  • MZ = 100% DZ = 50%
  • MZ = 50% DZ = 50%
  • MZ = 25% DZ = 75%
  • MZ = 75% DZ = 25%

Question 11

Question
What are some of the limitations of twin studies? Select all that apply
Answer
  • Experiments are naturalistic so we cannot manipulate the surrounding environment
  • There are more fraternal twins than identical, which gives a less accurate picture of environmental influences
  • No random allocation
  • Some parents believe mistakenly believe their twins are monozygotic rather than dizygotic, and vice versa
  • Twin studies are considered unethical

Question 12

Question
What are some of the limitations of adoption studies? Select all that apply
Answer
  • No random allocation
  • Experimenters have to seek out flaws in environment due to screening
  • Parents are screened for eligibility, therefore not a lot of variation in immediate family environments
  • Children who know they are adopted may respond differently in a shared environment
  • Experiments are naturalistic so we cannot manipulate environment

Question 13

Question
What did Caspi et al (2003) discover in their study regarding vulnerability to depression?
Answer
  • That there is relatively the same risk for developing depression after 4 + stressful life events regardless of your genetic predispositions
  • That you are more likely to develop depression after 2+ stressful life events if you have 1 high risk gene, and one protective gene, than if you have 2 high risk genes
  • That possessing 2 protective genes means you are more vulnerable to depression
  • That the more high risk genes you possess, the less stressful life events it will take for you to become depressed

Question 14

Question
At age 7, Sarah began to demonstrate really sophisticated and eloquent writing skills for someone her age, and was very advanced in mathematics. Her parents noticed these talents and arranged for her to attend gifted and talented programs within the school. What gene-environment correlation does this represent?
Answer
  • Passive
  • Evocative
  • Active
  • Inactive

Question 15

Question
What are some environmental risks to a child before pregnancy? Select all that apply
Answer
  • Mother's genetic makeup
  • History of substance abuse, or toxin exposure in the mother or father
  • Age of mother and father at time of conception
  • Paternal chronic illness
  • Inadequate nutrition in childhood or adolescence of the mother

Question 16

Question
At what phase during pregnancy is most vulnerable to the impact of teratogens?
Answer
  • Foetal
  • Germinal
  • Embyronic

Question 17

Question
At what phase, and how many weeks along, does the heartbeat develop?
Answer
  • Germinal period, 2 weeks
  • Embryonic period, 3 weeks
  • Embryonic period, 4 weeks
  • It varies for every child

Question 18

Question
How can teratogens impact the foetus during the Foetal period of pregnancy?
Answer
  • They rarely influence at this stage of pregnancy
  • This is the time they are most susceptible, and major structural abnormalities can occur
  • This is the time they are most susceptible, and major structural abnormalities occur in the organ systems
  • There is less of an impact, but it is still vulnerable to minor structural abnormalities, as well as damage to certain organ systems

Question 19

Question
Which phase of pregnancy is the most rapid period of development?
Answer
  • Germinal
  • Embryonic
  • Foetal

Question 20

Question
How many weeks along is it regular for foetus to develop a circadian rhythm?
Answer
  • 18 - 20
  • 12
  • 24
  • 28

Question 21

Question
What are some characteristics of the mother that can impact development during pregnancy? Select all that apply.
Answer
  • The dialogue she engages in
  • Age
  • Short, intense periods of stress
  • Prolonged periods of stress
  • Physical health

Question 22

Question
What are some early risks to postnatal development? Select all that apply
Answer
  • Parental temperament
  • Toxin exposure during pregnancy
  • Premature labour
  • Caregiving capacity of parents
  • Living circumstances of parents

Question 23

Question
A new mother develops postpartum depression, and as a result, takes less care of herself, and further engages in risky behaviours such as excessive drinking or smoking. What is this a good example of?
Answer
  • Additive risk model
  • Negative factors
  • Multiple stressor model
  • Cumulative risk model
