  1. 1Which of the following best describes DNA?
    1. ADNA stands for deoxyribonucleic acid, and contains all of the genetic information required for features of our bodies
    2. BDNA stands for deoxyribonucleic acid, and sends messages to our brain about how to control our bodily movements
    3. CDNA is an inherited script, based upon our environmental interactions early on in life
    4. DDNA is something that we all carry, but only utilise it in conscious situations
  2. 2If a father's sperm contains an X chromosome, when paired with a mother's egg, the resulting child:
    1. AWill not have its sex determined until after 8 weeks gestation
    2. BWill be male
    3. CWill inherit both male and female characteristics
    4. DWill be female
  3. 3To be expressed, a dominant gene:
    1. AMust have its pair in order to be expressed
    2. BWill be expressed regardless if a recessive gene is present
    3. CWill not be expressed if a recessive gene is present
    4. DIs expressed in combination with the recessive gene
  4. 4If blue eye color is a recessive gene, then in order for a person to have a phenotype of blue eyes:
    1. ATwo blue eye genes must be present
    2. BAs long as one blue eye gene is present, the trait will be expressed in the phenotype
    3. CBlue eye color is expressed randomly, there is no genetic pattern
    4. DBlue eye recessive genes will dominate over dominant genes of, for example, brown eyes
  5. 5A gene showing co-dominance:
    1. AHas one allele that is dominant to the other
    2. BHas two alleles that are equal in dominance
    3. CHas alleles linked tightly on the same chromosome
    4. DHas alleles which are recessive to each other
  6. 6Identify the differences between a genotype and phenotype:
    1. AA genotype is the genes carried by a person; the phenotype is the observable expression of the genes
    2. BA phenotype is the genes carried by a person; the genotype is the observable expression of the genes
    3. CA genotype carries all of the genes from your mother; A phenotype carries all of the genes from your father
    4. DA genotype is the observable expression of the genes; A phenotype is all of the alleles that you carry
  7. 7Place the three phases of prenatal development in the correct procedural order:
    1. AGerminal, foetal, embryonic
    2. BGerminal, embryonic, foetal
    3. CEmbryonic, germinal, foetal
    4. DEmbryonic, foetal, germinal
  8. 8Which of the following correctly matches the layers of the embryonic disc with the structures that they form, with ectoderm, mesoderm, and endoderm respectively?
    1. Athe nervous system, skin and hair; muscles, bones, circulatory system and other internal organs; the digestive system, lungs, urinary tract and glands
    2. Bthe digestive system, lungs, urinary tract and glands; muscles, bones, circulatory system and other internal organs; the nervous system, skin and hair
    3. Cmuscles, bones, circulatory system and other internal organs; the digestive system, lungs, urinary tract and glands; the nervous system, skin and hair
    4. Dthe nervous system, skin and hair; the digestive system, lungs, urinary tract and glands; muscles, bones, circulatory system and other internal organs
  9. 9Which of the following occur during the embryonic period?
    1. AAll basic organs of the body are formed, and the embryo begins to respond to direct stimulation
    2. BOrgans take on their final form and begin to function
    3. CAn inner membrane, called the amnion, forms a watertight sac with amniotic fluid to protect the developing organism
    4. DImplantation
  10. 10During which trimester does the foetus begin to move and kick, as well as develop the sucking and swallowing complexes?
    1. ATrimester 1
    2. BTrimester 2
    3. CTrimester 3
    4. DWithin two weeks of birth
