Questions and Answers
  • 1. 

    Who identified Down Syndrome as a chromosome 21 trisomy?

    • A.

      John Langdon Down

    • B.

      Jérôme Lejeune

    • C.

      Robert Bunsen

    Correct Answer
    B. Jérôme Lejeune
    Explanation
    Jérôme Lejeune is credited with identifying Down Syndrome as a chromosome 21 trisomy. He made this discovery in 1958 and was the first to establish the genetic basis for the condition. Lejeune's work was groundbreaking and revolutionized our understanding of Down Syndrome, leading to advancements in diagnosis and treatment. His contribution to the field of genetics and his dedication to improving the lives of individuals with Down Syndrome are widely recognized and respected.

    Rate this question:

  • 2. 

    A person with Down Syndrome has how many chromosomes?

    • A.

      46

    • B.

      47

    • C.

      23

    Correct Answer
    B. 47
    Explanation
    A person with Down Syndrome has 47 chromosomes. Typically, individuals have 46 chromosomes, with 23 pairs. However, individuals with Down Syndrome have an extra copy of chromosome 21, resulting in a total of 47 chromosomes. This additional chromosome causes the characteristic physical features and developmental delays associated with Down Syndrome.

    Rate this question:

  • 3. 

    Which is a disease that may result from Down Syndrome?

    • A.

      Celiac disease

    • B.

      Cancer

    • C.

      Cellulitis

    Correct Answer
    A. Celiac disease
    Explanation
    Celiac disease is a possible disease that may result from Down Syndrome. Down Syndrome is a genetic disorder caused by the presence of an extra chromosome 21, which can affect various body systems. Celiac disease is an autoimmune disorder where the immune system reacts to gluten, a protein found in wheat, barley, and rye. Individuals with Down Syndrome have a higher risk of developing celiac disease compared to the general population. This is believed to be due to the immune system abnormalities associated with Down Syndrome.

    Rate this question:

  • 4. 

    People with Down Syndrome usually will have an IQ of...

    • A.

      20-30

    • B.

      40-50

    • C.

      60-70

    Correct Answer
    B. 40-50
    Explanation
    People with Down Syndrome usually have an IQ range of 40-50. Down Syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. This extra genetic material affects the development of the brain and leads to intellectual disabilities. The average IQ for individuals with Down Syndrome is around 50, which is considered mild to moderate intellectual disability. However, it's important to note that IQ scores can vary among individuals with Down Syndrome, and some may have higher or lower scores within this range.

    Rate this question:

  • 5. 

    The chances of a mother's offspring having Down Syndrome ______ as the mother's age increases.

    • A.

      Increases

    • B.

      Decreases

    • C.

      Remains the same

    Correct Answer
    A. Increases
    Explanation
    As a mother's age increases, the chances of her offspring having Down Syndrome increase. This is because there is a higher likelihood of genetic abnormalities occurring in the eggs as women age. The risk of having a child with Down Syndrome is significantly higher in women over the age of 35 compared to younger women. Therefore, the correct answer is "increases".

    Rate this question:

  • 6. 

    True or False: A doctor can easilly tell if a baby will have Down Syndrome.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A doctor cannot easily tell if a baby will have Down Syndrome. While certain prenatal tests can indicate a higher risk of Down Syndrome, a definitive diagnosis can only be made through diagnostic testing such as amniocentesis or chorionic villus sampling. These tests involve analyzing the baby's chromosomes to determine if there is an extra copy of chromosome 21, which is characteristic of Down Syndrome. Therefore, it requires specific testing and cannot be easily determined just by a doctor's observation or examination.

    Rate this question:

  • 7. 

    Which is not a behavioral symptom of Down Syndrome?

    • A.

      Impulsive behavior

    • B.

      Poor judgment

    • C.

      Long attention span

    Correct Answer
    C. Long attention span
    Explanation
    Down Syndrome is a genetic disorder that typically results in certain physical and cognitive impairments. One common characteristic of individuals with Down Syndrome is a shorter attention span compared to neurotypical individuals. Therefore, a long attention span would not be a behavioral symptom of Down Syndrome.

    Rate this question:

  • 8. 

    Down Syndrome is _____.

    • A.

      Chromosomal

    • B.

      Sex-linked

    • C.

      Recessive

    Correct Answer
    A. Chromosomal
    Explanation
    Down Syndrome is a genetic disorder caused by an extra copy of chromosome 21. This additional genetic material affects the development and functioning of the body and brain. It is characterized by physical and intellectual disabilities, as well as certain health problems. The term "chromosomal" accurately describes the nature of Down Syndrome as it is caused by an abnormality in the chromosomes.

    Rate this question:

  • 9. 

    Down Syndrome is also called what?

    • A.

      John Langdon Down's Syndrome

    • B.

      Up Syndrome

    • C.

      Trisomy 21

    Correct Answer
    C. Trisomy 21
    Explanation
    Trisomy 21 is the correct answer because it refers to the genetic condition in which a person has three copies of chromosome 21 instead of the usual two. This extra genetic material leads to the characteristic features and developmental delays associated with Down Syndrome. The term "Down Syndrome" is commonly used to describe this condition, but "Trisomy 21" is the more accurate and scientific name for it. "John Langdon Down's Syndrome" is not a recognized term for this condition, and "Up Syndrome" is not a valid or commonly used name for it.

    Rate this question:

  • 10. 

    True or False: Less than a generation ago, children with Down Syndrome did not survive beyond their teen years.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Less than a generation ago, children with Down Syndrome did not survive beyond their teen years. This is because medical advancements and improved healthcare have significantly increased the life expectancy of individuals with Down Syndrome. With better access to medical care, early interventions, and support, individuals with Down Syndrome can now live well into adulthood and even old age.
