the experience and qualifications that a person earns during his/her lifetime are example of acquired traits. They are due to change in lifestyle, injury, loss of body parts etc. These traits cannot be inherited. Only the changes in the genetic material of the reproductive cells can be inherited.
e.g. 1. muscles developed by strenuous exercise cannot be inherited to offspring as these changes occur in somatic cells ( changes in the somatic cells are not passes onto the next generation). These are called as acquired traits.
2. if a person read books, the knowledge he earns by reading the book does not make any change in the gene, hence this knowledge will not get automatically transmitted to his generation.
