What is meant by discontinuous variation?

When a charateristic only has a few possible outcomes (e.g. blue, green, brown - eye colour)

2

How do we present continuous variation?

As a histogram

What is meant by continuous variation?

When a characteristic can have a whole range of values (e.g. height)

10

Characteristics that only occur due to inherited variation show which type of variation? Continuous or discontinuous?

Discontinuous (only a few possible outcomes)

11

Characteristics that only occur due to inherited AND environmental variation show which type of variation? Continuous or discontinuous?

Continuous (many possible outcomes - e.g. height)

12

What do we call the curved line that we usually dray to show the trend of a histogram?

A normal distribution curve
