Variation in Population
Biology · 50 practice questions
Morphological variation (size, colour, fingerprints); physiological variation (tongue-rolling, PTC tasting, blood groups); application of discontinuous variation in crime detection, blood transfusion and paternity determination.
- Differentiate between continuous and discontinuous variation and relate variation to environment, habitat and genetic constitution.
- Measure and plot frequency distributions of height/weight.
- Apply fingerprint classification in identity detection.
- Apply knowledge of blood groups in transfusion, paternity determination and crime detection.
Try a few questions
- Practice question 1
Recognizing variation among individual patients specifically is practically important mainly when
- A.a factor entirely unrelated to diagnosing or treating disease of any kind
- B.measuring rainfall, a task entirely unrelated to variation among patients
- C.classifying rocks and minerals, a task unrelated to individual patient variation
- D.diagnosing and treating disease
Show the answer
D. diagnosing and treating disease
Recognizing variation among individual patients specifically is practically important mainly when diagnosing and treating disease.
- Practice question 2
Disease resistance, within a population, specifically can vary among individuals mainly due to
- A.their own precise geographic location, considered on its own
- B.a factor entirely unrelated to genetic differences affecting immune response
- C.the exact colour of their own skin or fur, with no genetic basis at all
- D.genetic differences affecting their immune response
Show the answer
D. genetic differences affecting their immune response
Disease resistance, within a population, specifically can vary among individuals mainly due to genetic differences affecting immunity.
- Practice question 3
Height within a human population, when plotted as a graph, specifically tends to follow a
- A.a factor entirely unrelated to a bell-shaped distribution curve of any kind
- B.bell-shaped (normal) distribution curve
- C.perfectly flat, horizontal line with no variation of any kind at all
- D.distribution that always shows exactly two separate, distinct peaks
Show the answer
B. bell-shaped (normal) distribution curve
Height within a human population, when plotted as a graph, specifically tends to follow a bell-shaped (normal) distribution curve.
