Understanding Continuous and Discontinuous Variation

What does the term 'variation' refer to in the context of biology?

• Differences in features among individuals

• The process of evolution

• The genetic makeup of an organism

• The habitat of a species

Which of the following is an example of continuous variation?

• Eye color

• Species of tree

• Tail length

• Blood type

How is continuous variation typically measured?

• Through genetic analysis

• With numerical values

• Using categories

• By observing behavior

Which characteristic is an example of discontinuous variation?

• Height

• Leaf width

• Weight

• Fur color

How is discontinuous variation represented graphically?

• Line graph

• Scatter plot

• Pie chart

• Bar graph

What shape does a histogram of continuous variation typically form?

• A straight line

• A flat line

• A bell-shaped curve

• A zigzag pattern

Which of the following is NOT a category used in discontinuous variation?

• Tail length

• Species of tree

• Blood type

• Fur color

What type of graph is used to show continuous variation?

• Bar graph

• Line graph

• Histogram

• Pie chart

Which of the following is a continuous variation?

• Blood type

• Eye color

• Species of tree

• Weight

What is the key difference between continuous and discontinuous variation?

• Continuous variation is measured in categories, while discontinuous is measured numerically.

• Continuous variation is measured numerically, while discontinuous is measured in categories.

• Continuous variation is always genetic, while discontinuous is environmental.

• Continuous variation is always environmental, while discontinuous is genetic.
