In biology, even within the same species, individuals are not identical. Think about people you know – they have different heights, eye colours, and so on. These differences are known as variation.
Quiz#2
What is the biological term for the differences between individuals of the same species?
variation
Lesson#3
Variation can be classified into two main types. The first is continuous variation, where characteristics can have any value within a range. For example, people aren't just 'tall' or 'short'; there's a whole range of heights in between.
Quiz#4
What type of variation shows a range of phenotypes between two extremes?
continuous variation
Lesson#5
Common examples of continuous variation in humans are features that you can measure, such as body length, also known as height, and body mass.
Quiz#6
Body length and body mass are examples of what type of variation?
continuous variation
