With the help of one example for each, distinguish between the acquired traits and the inherited traits., Why are the traits/experiences acquired during the entire lifetime of an individual not inherited in the next generation? Explain the reason of this fact with an example.
Answer:
|
Acquired Traits |
Inherited Traits |
|
These traits are acquired by a person during their lifetime. |
These traits are inherited by the individual from their parents. |
|
Not passed onto the next generation |
They are passed onto the next generation |
|
Cannot direct evolution |
Can direct evolution |
|
Example: Body weight, knowledge, sense of humor, etc |
Example: Color of eye, color of skin, hair type , etc. |
Traits acquired during the lifetime of an individual do not reflect in the reproductive tissues .
Changes in the non-reproductive tissues are not passed on to the DNA of the germ cells and therefore not inherited by the next generation.
Example: The change in body weight of beetles due to starvation is not passed onto the next generation since it does not make any change in the germ cells of the beetle.
