Question
The following information is about two individuals, X and Y.
*Individual X: presence of a dimple
*Individual Y: no dimple
Which of the following factors causes the difference in the trait between the two individuals?
- Mutation
- Genetics
- Hormone
- Environment
Hint:
Trait is inherited.
The correct answer is: Genetics
No two individual appears same. This is due to the difference in the genetic make up of the individuals of the same population which is named as variation.
Variation can be due to the influence of genetic material or environment.
Variations like height, weight, skin color are due to combination of genes and environmental factors. The variation cannot be limited to a specific range in these traits.
Certain variations like dimples, blood group, eye color have limited range of expression. A person can have dimple or not. This is due to the expression of the particular gene. Environment does not effect this type of trait. This type of variation is called discontinuous variation.
- Traits under discontinuous variation have limited range
- Traits under continuous variation have unlimited range
- Discontinuous variation is due to the influence of genes alone
- Continuous variation is due to the combined effects of genes and environment
