Tabulate two distinguishing features between acquired traits and inherited traits with one example of each.
✓

Answer

  1. Characters that are passed on from parents to offspring are inherited characters.
For example: colour of seeds, colour of eyes, etc.
  1. Characters appearing in an individual’s lifetime but cannot be transmitted to next generation are acquired characters.
For example: obese body, loss of a finger in an accident, etc.
Acquired Inherited
The acquired traits are the traits which are experienced by an indiavidul during his life time. Inherited traits are distinguishing qualites of characteristics which one acquires from the ancestors.
The acquired traits of an organism cannot be passed on to its future generations. The inherited traits of an organism are passed on to its future generations.
For e.g, 'low weight' of beetle. ' cut tail' of a mouse. For e.g., red colour of beetles, fur coat of guinea pigs.
