Question
Differences that exist naturally among members of a population or species are called ___?
- Mutation
- Adaptation
- Variations
- Evolution
Hint:
Eye color, height, weight, blood group are few examples.
The correct answer is: Variations
Variation refers to the difference in the genetic make up among individuals of the same species.
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
