Question
Which one of the following shows discontinuous variation?
- Eye color
- Height
- Strength
- Weight
Hint:
Variations associated with this trait is limited.
The correct answer is: Eye color
Genetic make up of every individual in a species varies. This is called variation.
Variations can be classified broadly into continuous and discontinuous variation.
In continuous variation, the parameter under study does not have a specific range. For example, height of an individual.
In discontinuous variation, the parameter under study will be limited to specific number or range as in case of blood groups or eye color.
- Genetic variation is the reason for difference among individuals within the same species
- Variations can be continuous or discontinuous
- Discontinuous variation of a trait is limited to specific number as in eye color or blood groups
