Question : 14
Total: 36
"We cannot pass on to our progeny the experiences and qualifications earned during our life time". Justify the statement giving reason and examples.
Solution:  
Acquired knowledge or skills like dancing, music etc. do not bring any change in the DNA of the reproducing cell or germ cell. Only germ cells are responsible for passing on the characters from the parents to the progeny. Thus due to this fact the characters which we inherit during our life time are not passed to our progeny.
