CBSE Class 10 Science 2017 · Paper 31/3/C · Question 5
List in tabular form any two distinguishing features between the acquired traits and the inherited traits.
Answer
Acquired traits develop in one's lifetime and are not passed on; inherited traits come from parents' genes and are passed on.
Distinguishing features (the table is shown in step 2):
1. Origin — Acquired traits develop during the lifetime of an individual, through its experiences or surroundings (e.g. the low weight of a starved beetle, a skill that has been learnt). Inherited traits are received from the parents through their genes (e.g. eye colour).
2. Transmission — Acquired traits are changes in body (non-reproductive) tissues and are not passed on to the next generation. Inherited traits are coded in the DNA of the germ cells and are passed on from one generation to the next.
