Question
What is meant by acquired and inherited traits? Explain with one example each.
✓

Answer

A trait of an organism which is ‘not inherited’ but develops in response to the environment is called an acquired trait.
Example: If a beetle does not get sufficient food for a considerable time, its weight will be reduced due to starvation. The low weight of the beetle is an example of acquired trait. A trait of an organism which is caused by a change in its genes (DNA) is called an inherited trait.
Example: The change of colour from red beetle to green beetle is an example of inherited trait.
