Question

we cannot pass on to our progeny the experiences and qualifications earned during our lifetime . justify the statemment. give reasons and exampes

Answer 1

The traits which are earned by us during our lifetime are known as aquired traits and these traits don't belong to the dna or any of the characteristics and more over its only to the physical part and this does not create any chemical changes in our body so ,traits are passed to the progeny only if the traits are chemically connected to our body and  if they are inherited from our parents they will be passed if not they will not be passed  . To say in simple words traits which are present in DNA will be passed on and traits which are acquired by us and there is no linkage with the metabolism and DNA

Answer 2

"We cannot pass on to our progeny the experiences and qualifications earned during our life time since the experiences and qualifications are examples of acquired traits and these are not inherited but develop during the lifetime of an individual which cannot be passed on to next generations. Note- Inherited traits are those which are obtained from parents or caused by a change in its genes (or DNA). These are the ones which are transmitted to future generations. Example- If we breed some mice, all the progeny of mice will have tails, just like parents. Now, if we cut the tails of these first generation mice surgically and breed them, we will get new mice, all with full tails. Despite the cutting of tails of mice for a number of generations, a tailless mouse is never born. This is because the cut tail of mice is an acquired trait which is never passed on to their progeny. This is because cutting the tails of mice does not change the genes of their reproductive cells.
