With the help of two suitable examples, explain why certain experiences and traits earned by people during their lifetime are not passed on to their next generations. When can such traits be passed on?

There are certain characters or traits developed during the lifetime of an individual and are known as the acquired characters. There are traits which are expressed just physically and do not have any genetic significance like an increase in the weight and length of the hair. These traits are generally not passed on to the next generation as there are no genes which are coding for these traits. If these acquired traits are developed due to some type of genetic mutation, then the character can be passed on to the next generation.
